Documentation

Overview

Package spanner provides access to the Cloud Spanner API.

This package is DEPRECATED. Use package cloud.google.com/go/spanner instead.

For product documentation, see: https://cloud.google.com/spanner/

Creating a client

Usage example: 

import "google.golang.org/api/spanner/v1"
...
ctx := context.Background()
spannerService, err := spanner.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use option.WithScopes: 

spannerService, err := spanner.NewService(ctx, option.WithScopes(spanner.SpannerDataScope))

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey: 

spannerService, err := spanner.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource: 

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
spannerService, err := spanner.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

Types

type Backup 

type Backup struct {
	// CreateTime: Output only. The backup will contain an externally
	// consistent
	// copy of the database at the timestamp specified by
	// `create_time`. `create_time` is approximately the time
	// the
	// CreateBackup request is received.
	CreateTime string `json:"createTime,omitempty"`

	// Database: Required for the CreateBackup operation.
	// Name of the database from which this backup was
	// created. This needs to be in the same instance as the backup.
	// Values are of the
	// form
	// `projects/<project>/instances/<instance>/databases/<database>`.
	Database string `json:"database,omitempty"`

	// ExpireTime: Required for the CreateBackup
	// operation. The expiration time of the backup, with
	// microseconds
	// granularity that must be at least 6 hours and at most 366 days
	// from the time the CreateBackup request is processed. Once the
	// `expire_time`
	// has passed, the backup is eligible to be automatically deleted by
	// Cloud
	// Spanner to free the resources used by the backup.
	ExpireTime string `json:"expireTime,omitempty"`

	// Name: Output only for the CreateBackup operation.
	// Required for the UpdateBackup operation.
	//
	// A globally unique identifier for the backup which cannot be

ExecuteBatchDmlResponse: The response for ExecuteBatchDml. Contains a list of ResultSet messages, one for each DML statement that has successfully executed, in the same order as the statements in the request. If a statement fails, the status in the response body identifies the cause of the failure.

To check for DML statements that failed, use the following approach:

1. Check the status in the response message. The google.rpc.Code enum 

value `OK` indicates that all statements were executed

successfully. 2. If the status was not `OK`, check the number of result sets in the 

response. If the response contains `N` ResultSet messages, then
statement `N+1` in the request failed.

Example 1:

* Request: 5 DML statements, all executed successfully. * Response: 5 ResultSet messages, with the status `OK`.

Example 2:

* Request: 5 DML statements. The third statement has a syntax error. * Response: 2 ResultSet messages, and a syntax error (`INVALID_ARGUMENT`) 

status. The number of ResultSet messages indicates that the third
statement failed, and the fourth and fifth statements were not

executed.

KeyRange: KeyRange represents a range of rows in a table or index.

A range has a start key and an end key. These keys can be open or closed, indicating if the range includes rows with that key.

Keys are represented by lists, where the ith value in the list corresponds to the ith component of the table or index primary key. Individual values are encoded as described here.

For example, consider the following table definition: 

CREATE TABLE UserEvents (
  UserName STRING(MAX),
  EventDate STRING(10)
) PRIMARY KEY(UserName, EventDate);

The following keys name rows in this table: 

"Bob", "2014-09-23"

Since the `UserEvents` table's `PRIMARY KEY` clause names two columns, each `UserEvents` key has two elements; the first is the `UserName`, and the second is the `EventDate`.

Key ranges with multiple components are interpreted lexicographically by component using the table or index key's declared sort order. For example, the following range returns all events for user "Bob" that occurred in the year 2015: 

"start_closed": ["Bob", "2015-01-01"]
"end_closed": ["Bob", "2015-12-31"]

Start and end keys can omit trailing key components. This affects the inclusion and exclusion of rows that exactly match the provided key components: if the key is closed, then rows that exactly match the provided components are included; if the key is open, then rows that exactly match are not included.

For example, the following range includes all events for "Bob" that occurred during and after the year 2000: 

"start_closed": ["Bob", "2000-01-01"]
"end_closed": ["Bob"]

The next example retrieves all events for "Bob": 

"start_closed": ["Bob"]
"end_closed": ["Bob"]

To retrieve events before the year 2000: 

"start_closed": ["Bob"]
"end_open": ["Bob", "2000-01-01"]

The following range includes all rows in the table: 

"start_closed": []
"end_closed": []

This range returns all users whose `UserName` begins with any character from A to C: 

"start_closed": ["A"]
"end_open": ["D"]

This range returns all users whose `UserName` begins with B: 

"start_closed": ["B"]
"end_open": ["C"]

Key ranges honor column sort order. For example, suppose a table is defined as follows: 

CREATE TABLE DescendingSortedTable {
  Key INT64,
  ...
) PRIMARY KEY(Key DESC);

The following range retrieves all rows with key values between 1 and 100 inclusive: 

"start_closed": ["100"]
"end_closed": ["1"]

Note that 100 is passed as the start, and 1 is passed as the end, because `Key` is a descending column in the schema.

}

KeySet: `KeySet` defines a collection of Cloud Spanner keys and/or key ranges. All the keys are expected to be in the same table or index. The keys need not be sorted in any particular way.

If the same key is specified multiple times in the set (for example if two ranges, two keys, or a key and a range overlap), Cloud Spanner behaves as if the key were only specified once.

	//     # because they are lists. Recursively, the last and first
	// elements
	//     # of the inner lists are merged because they are strings.
	//     ["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"]

	// **Important:** If you use IAM Conditions, you must include the `etag`

Policy: An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources.

A `Policy` is a collection of `bindings`. A `binding` binds one or more `members` to a single `role`. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role.

Optionally, a `binding` can specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both.

**JSON example:** 

{
  "bindings": [
    {
      "role": "roles/resourcemanager.organizationAdmin",
      "members": [
        "user:mike@example.com",
        "group:admins@example.com",
        "domain:google.com",

"serviceAccount:my-project-id@appspot.gserviceaccount.com" 

  ]
},
{
  "role": "roles/resourcemanager.organizationViewer",
  "members": ["user:eve@example.com"],
  "condition": {
    "title": "expirable access",
    "description": "Does not grant access after Sep 2020",
    "expression": "request.time <

timestamp('2020-10-01T00:00:00.000Z')", 

      }
    }
  ],
  "etag": "BwWWja0YfJA=",
  "version": 3
}

**YAML example:** 

bindings:
- members:
  - user:mike@example.com
  - group:admins@example.com
  - domain:google.com
  - serviceAccount:my-project-id@appspot.gserviceaccount.com
  role: roles/resourcemanager.organizationAdmin
- members:
  - user:eve@example.com
  role: roles/resourcemanager.organizationViewer
  condition:
    title: expirable access
    description: Does not grant access after Sep 2020
    expression: request.time <

timestamp('2020-10-01T00:00:00.000Z')

The comparison operator must be one of: `<`, `>`, `<=`, `>=`, `!=`, `=`, or `:`. Colon `:` is the contains operator. Filter rules are not case sensitive.

The following fields in the operation are eligible for filtering:

  • `name` - The name of the long-running operation
  • `done` - False if the operation is in progress, else true.
  • `metadata.@type` - the type of metadata. For example, the type

string 

for CreateBackupMetadata is

`type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMeta data`.

  • `metadata.<field_name>` - any field in metadata.value.
  • `error` - Error associated with the long-running operation.
  • `response.@type` - the type of response.
  • `response.<field_name>` - any field in response.value.

You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic, but you can specify AND, OR, and NOT logic explicitly.

Here are a few examples:

  • `done:true` - The operation is complete.
  • `metadata.database:prod` - The database the backup was taken from

has 

   a name containing the string "prod".
*

`(metadata.@type=type.googleapis.com/google.spanner.admin.database.v1. CreateBackupMetadata) AND` <br/> 

`(metadata.name:howl) AND` <br/>
`(metadata.progress.start_time < \"2018-03-28T14:50:00Z\") AND`

<br/> 

`(error:*)` - Returns operations where:
* The operation's metadata type is CreateBackupMetadata.
* The backup name contains the string "howl".
* The operation started before 2018-03-28T14:50:00Z.
* The operation resulted in an error.

func (*ProjectsInstancesBackupsOperationsService) Cancel 

func (r *ProjectsInstancesBackupsOperationsService) Cancel(name string) *ProjectsInstancesBackupsOperationsCancelCall

Cancel: Starts asynchronous cancellation on a long-running operation. 

The server

makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to `Code.CANCELLED`.

func (*ProjectsInstancesBackupsOperationsService) Delete 

func (r *ProjectsInstancesBackupsOperationsService) Delete(name string) *ProjectsInstancesBackupsOperationsDeleteCall

func (*ProjectsInstancesBackupsOperationsService) List 

func (r *ProjectsInstancesBackupsOperationsService) List(name string) *ProjectsInstancesBackupsOperationsListCall

List: Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns `UNIMPLEMENTED`.

NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/*/operations`. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

func (*ProjectsInstancesDatabaseOperationsListCall) Filter 

func (c *ProjectsInstancesDatabaseOperationsListCall) Filter(filter string) *ProjectsInstancesDatabaseOperationsListCall

Filter sets the optional parameter "filter": An expression that filters the list of returned operations.

A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: `<`, `>`, `<=`, `>=`, `!=`, `=`, or `:`. Colon `:` is the contains operator. Filter rules are not case sensitive.

The following fields in the Operation are eligible for filtering:

  • `name` - The name of the long-running operation
  • `done` - False if the operation is in progress, else true.
  • `metadata.@type` - the type of metadata. For example, the type

string 

for RestoreDatabaseMetadata is

`type.googleapis.com/google.spanner.admin.database.v1.RestoreDatabaseM etadata`.

  • `metadata.<field_name>` - any field in metadata.value.
  • `error` - Error associated with the long-running operation.
  • `response.@type` - the type of response.
  • `response.<field_name>` - any field in response.value.

You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic. However, you can specify AND, OR, and NOT logic explicitly.

Here are a few examples:

  • `done:true` - The operation is complete. *

`(metadata.@type=type.googleapis.com/google.spanner.admin.database.v1. RestoreDatabaseMetadata) AND` <br/> 

`(metadata.source_type:BACKUP) AND` <br/>
`(metadata.backup_info.backup:backup_howl) AND` <br/>
`(metadata.name:restored_howl) AND` <br/>
`(metadata.progress.start_time < \"2018-03-28T14:50:00Z\") AND`

<br/> 

`(error:*)` - Return operations where:
* The operation's metadata type is RestoreDatabaseMetadata.
* The database is restored from a backup.
* The backup name contains "backup_howl".
* The restored database's name contains "restored_howl".
* The operation started before 2018-03-28T14:50:00Z.
* The operation resulted in an error.

func (*ProjectsInstancesDatabasesOperationsService) Cancel 

func (r *ProjectsInstancesDatabasesOperationsService) Cancel(name string) *ProjectsInstancesDatabasesOperationsCancelCall

Cancel: Starts asynchronous cancellation on a long-running operation. 

The server

makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to `Code.CANCELLED`.

NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/*/operations`. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

func (*ProjectsInstancesDatabasesSessionsService) BatchCreate 

func (r *ProjectsInstancesDatabasesSessionsService) BatchCreate(database string, batchcreatesessionsrequest *BatchCreateSessionsRequest) *ProjectsInstancesDatabasesSessionsBatchCreateCall

BatchCreate: Creates multiple new sessions.

This API can be used to initialize a session cache on the clients. See https://goo.gl/TgSFN2 for best practices on session cache management.

func (*ProjectsInstancesDatabasesSessionsService) BeginTransaction 

func (r *ProjectsInstancesDatabasesSessionsService) BeginTransaction(session string, begintransactionrequest *BeginTransactionRequest) *ProjectsInstancesDatabasesSessionsBeginTransactionCall

BeginTransaction: Begins a new transaction. This step can often be skipped: Read, ExecuteSql and Commit can begin a new transaction as a side-effect.

func (*ProjectsInstancesDatabasesSessionsService) Commit 

func (r *ProjectsInstancesDatabasesSessionsService) Commit(session string, commitrequest *CommitRequest) *ProjectsInstancesDatabasesSessionsCommitCall

Commit: Commits a transaction. The request includes the mutations to be applied to rows in the database.

`Commit` might return an `ABORTED` error. This can occur at any time; commonly, the cause is conflicts with concurrent transactions. However, it can also happen for a variety of other reasons. If `Commit` returns `ABORTED`, the caller should re-attempt the transaction from the beginning, re-using the same session.

func (*ProjectsInstancesDatabasesSessionsService) Create 

func (r *ProjectsInstancesDatabasesSessionsService) Create(database string, createsessionrequest *CreateSessionRequest) *ProjectsInstancesDatabasesSessionsCreateCall

Create: Creates a new session. A session can be used to perform transactions that read and/or modify data in a Cloud Spanner database. Sessions are meant to be reused for many consecutive transactions.

Sessions can only execute one transaction at a time. To execute multiple concurrent read-write/write-only transactions, create multiple sessions. Note that standalone reads and queries use a transaction internally, and count toward the one transaction limit.

Active sessions use additional server resources, so it is a good idea to delete idle and unneeded sessions. Aside from explicit deletes, Cloud Spanner may delete sessions for which no operations are sent for more than an hour. If a session is deleted, requests to it return `NOT_FOUND`.

Idle sessions can be kept alive by sending a trivial SQL query periodically, e.g., "SELECT 1".

func (*ProjectsInstancesDatabasesSessionsService) Delete 

func (r *ProjectsInstancesDatabasesSessionsService) Delete(name string) *ProjectsInstancesDatabasesSessionsDeleteCall

Delete: Ends a session, releasing server resources associated with it. This will asynchronously trigger cancellation of any operations that are running with this session.

func (*ProjectsInstancesDatabasesSessionsService) ExecuteBatchDml 

func (r *ProjectsInstancesDatabasesSessionsService) ExecuteBatchDml(session string, executebatchdmlrequest *ExecuteBatchDmlRequest) *ProjectsInstancesDatabasesSessionsExecuteBatchDmlCall

ExecuteBatchDml: Executes a batch of SQL DML statements. This method allows many statements to be run with lower latency than submitting them sequentially with ExecuteSql.

Statements are executed in sequential order. A request can succeed even if a statement fails. The ExecuteBatchDmlResponse.status field in the response provides information about the statement that failed. Clients must inspect this field to determine whether an error occurred.

Execution stops after the first failed statement; the remaining statements are not executed.

func (*ProjectsInstancesDatabasesSessionsService) ExecuteSql 

func (r *ProjectsInstancesDatabasesSessionsService) ExecuteSql(session string, executesqlrequest *ExecuteSqlRequest) *ProjectsInstancesDatabasesSessionsExecuteSqlCall

ExecuteSql: Executes an SQL statement, returning all results in a single reply. This method cannot be used to return a result set larger than 10 MiB; if the query yields more data than that, the query fails with a `FAILED_PRECONDITION` error.

Operations inside read-write transactions might return `ABORTED`. If this occurs, the application should restart the transaction from the beginning. See Transaction for more details.

Larger result sets can be fetched in streaming fashion by calling ExecuteStreamingSql instead.

func (*ProjectsInstancesDatabasesSessionsService) ExecuteStreamingSql 

func (r *ProjectsInstancesDatabasesSessionsService) ExecuteStreamingSql(session string, executesqlrequest *ExecuteSqlRequest) *ProjectsInstancesDatabasesSessionsExecuteStreamingSqlCall

ExecuteStreamingSql: Like ExecuteSql, except returns the result set as a stream. Unlike ExecuteSql, there is no limit on the size of the returned result set. However, no individual row in the result set can exceed 100 MiB, and no column value can exceed 10 MiB.

func (*ProjectsInstancesDatabasesSessionsService) Get 

func (r *ProjectsInstancesDatabasesSessionsService) Get(name string) *ProjectsInstancesDatabasesSessionsGetCall

Get: Gets a session. Returns `NOT_FOUND` if the session does not exist. This is mainly useful for determining whether a session is still alive.

func (*ProjectsInstancesDatabasesSessionsService) List 

func (r *ProjectsInstancesDatabasesSessionsService) List(database string) *ProjectsInstancesDatabasesSessionsListCall

List: Lists all sessions in a given database.

func (*ProjectsInstancesDatabasesSessionsService) PartitionQuery 

func (r *ProjectsInstancesDatabasesSessionsService) PartitionQuery(session string, partitionqueryrequest *PartitionQueryRequest) *ProjectsInstancesDatabasesSessionsPartitionQueryCall

PartitionQuery: Creates a set of partition tokens that can be used to execute a query operation in parallel. Each of the returned partition tokens can be used by ExecuteStreamingSql to specify a subset of the query result to read. The same session and read-only transaction must be used by the PartitionQueryRequest used to create the partition tokens and the ExecuteSqlRequests that use the partition tokens.

Partition tokens become invalid when the session used to create them is deleted, is idle for too long, begins a new transaction, or becomes too old. When any of these happen, it is not possible to resume the query, and the whole operation must be restarted from the beginning.

func (*ProjectsInstancesDatabasesSessionsService) PartitionRead 

func (r *ProjectsInstancesDatabasesSessionsService) PartitionRead(session string, partitionreadrequest *PartitionReadRequest) *ProjectsInstancesDatabasesSessionsPartitionReadCall

PartitionRead: Creates a set of partition tokens that can be used to execute a read operation in parallel. Each of the returned partition tokens can be used by StreamingRead to specify a subset of the read result to read. The same session and read-only transaction must be used by the PartitionReadRequest used to create the partition tokens and the ReadRequests that use the partition tokens. There are no ordering guarantees on rows returned among the returned partition tokens, or even within each individual StreamingRead call issued with a partition_token.

Partition tokens become invalid when the session used to create them is deleted, is idle for too long, begins a new transaction, or becomes too old. When any of these happen, it is not possible to resume the read, and the whole operation must be restarted from the beginning.

func (*ProjectsInstancesDatabasesSessionsService) Read 

func (r *ProjectsInstancesDatabasesSessionsService) Read(session string, readrequest *ReadRequest) *ProjectsInstancesDatabasesSessionsReadCall

Read: Reads rows from the database using key lookups and scans, as a simple key/value style alternative to ExecuteSql. This method cannot be used to return a result set larger than 10 MiB; if the read matches more data than that, the read fails with a `FAILED_PRECONDITION` error.

Reads inside read-write transactions might return `ABORTED`. If this occurs, the application should restart the transaction from the beginning. See Transaction for more details.

Larger result sets can be yielded in streaming fashion by calling StreamingRead instead.

func (*ProjectsInstancesDatabasesSessionsService) Rollback 

func (r *ProjectsInstancesDatabasesSessionsService) Rollback(session string, rollbackrequest *RollbackRequest) *ProjectsInstancesDatabasesSessionsRollbackCall

Rollback: Rolls back a transaction, releasing any locks it holds. It is a good idea to call this for any transaction that includes one or more Read or ExecuteSql requests and ultimately decides not to commit.

`Rollback` returns `OK` if it successfully aborts the transaction, the transaction was already aborted, or the transaction is not found. `Rollback` never returns `ABORTED`.

func (*ProjectsInstancesDatabasesSessionsService) StreamingRead 

func (r *ProjectsInstancesDatabasesSessionsService) StreamingRead(session string, readrequest *ReadRequest) *ProjectsInstancesDatabasesSessionsStreamingReadCall

StreamingRead: Like Read, except returns the result set as a stream. Unlike Read, there is no limit on the size of the returned result set. However, no individual row in the result set can exceed 100 MiB, and no column value can exceed 10 MiB.

func NewProjectsInstancesOperationsService 

func NewProjectsInstancesOperationsService(s *Service) *ProjectsInstancesOperationsService

func (*ProjectsInstancesOperationsService) Cancel 

func (r *ProjectsInstancesOperationsService) Cancel(name string) *ProjectsInstancesOperationsCancelCall

Cancel: Starts asynchronous cancellation on a long-running operation. 

The server

makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to `Code.CANCELLED`.

func (*ProjectsInstancesOperationsService) Delete 

func (r *ProjectsInstancesOperationsService) Delete(name string) *ProjectsInstancesOperationsDeleteCall

NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/*/operations`. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

func (*ProjectsInstancesService) Create 

func (r *ProjectsInstancesService) Create(parent string, createinstancerequest *CreateInstanceRequest) *ProjectsInstancesCreateCall

Create: Creates an instance and begins preparing it to begin serving. The returned long-running operation can be used to track the progress of preparing the new instance. The instance name is assigned by the caller. If the named instance already exists, `CreateInstance` returns `ALREADY_EXISTS`.

Immediately upon completion of this request:

  • The instance is readable via the API, with all requested

attributes 

but no allocated resources. Its state is `CREATING`.

Until completion of the returned operation:

  • Cancelling the operation renders the instance immediately

unreadable 

  via the API.
* The instance can be deleted.
* All other attempts to modify the instance are rejected.

Upon completion of the returned operation:

  • Billing for all successfully-allocated resources begins (some

types 

  may have lower than the requested levels).
* Databases can be created in the instance.
* The instance's allocated resource levels are readable via the

API.

  • The instance's state becomes `READY`.

The returned long-running operation will have a name of the format `<instance_name>/operations/<operation_id>` and can be used to track creation of the instance. The metadata field type is CreateInstanceMetadata. The response field type is Instance, if successful.

func (*ProjectsInstancesService) Delete 

func (r *ProjectsInstancesService) Delete(name string) *ProjectsInstancesDeleteCall

func (*ProjectsInstancesService) List 

func (r *ProjectsInstancesService) List(parent string) *ProjectsInstancesListCall

List: Lists all instances in the given project.

func (*ProjectsInstancesService) Patch 

func (r *ProjectsInstancesService) Patch(nameid string, updateinstancerequest *UpdateInstanceRequest) *ProjectsInstancesPatchCall

Patch: Updates an instance, and begins allocating or releasing resources as requested. The returned long-running operation can be used to track the progress of updating the instance. If the named instance does not exist, returns `NOT_FOUND`.

Immediately upon completion of this request:

  • For resource types for which a decrease in the instance's

allocation 

has been requested, billing is based on the newly-requested

level.

Until completion of the returned operation:

  • Cancelling the operation sets its metadata's cancel_time, and begins restoring resources to their pre-request values. The operation is guaranteed to succeed at undoing all resource changes, after which point it terminates with a `CANCELLED` status.
  • All other attempts to modify the instance are rejected.
  • Reading the instance via the API continues to give the

pre-request 

resource levels.

Upon completion of the returned operation:

  • Billing begins for all successfully-allocated resources (some

types 

  may have lower than the requested levels).
* All newly-reserved resources are available for serving the

instance's 

  tables.
* The instance's new resource levels are readable via the API.

The returned long-running operation will have a name of the format `<instance_name>/operations/<operation_id>` and can be used to track the instance modification. The metadata field type is UpdateInstanceMetadata. The response field type is Instance, if successful.

Authorization requires `spanner.instances.update` permission on resource name.

func (*ProjectsInstancesService) SetIamPolicy 

func (r *ProjectsInstancesService) SetIamPolicy(resource string, setiampolicyrequest *SetIamPolicyRequest) *ProjectsInstancesSetIamPolicyCall

TransactionOptions: # Transactions

Each session can have at most one active transaction at a time. After the active transaction is completed, the session can immediately be re-used for the next transaction. It is not necessary to create a new session for each transaction.

Transaction Modes

Cloud Spanner supports three transaction modes:

  1. Locking read-write. This type of transaction is the only way to write data into Cloud Spanner. These transactions rely on pessimistic locking and, if necessary, two-phase commit. Locking read-write transactions may abort, requiring the application to retry.

  2. Snapshot read-only. This transaction type provides guaranteed consistency across several reads, but does not allow writes. Snapshot read-only transactions can be configured to read at timestamps in the past. Snapshot read-only transactions do not need to be committed.

  3. Partitioned DML. This type of transaction is used to execute a single Partitioned DML statement. Partitioned DML partitions the key space and runs the DML statement over each partition in parallel using separate, internal transactions that commit independently. Partitioned DML transactions do not need to be committed.

For transactions that only read, snapshot read-only transactions provide simpler semantics and are almost always faster. In particular, read-only transactions do not take locks, so they do not conflict with read-write transactions. As a consequence of not taking locks, they also do not abort, so retry loops are not needed.

Transactions may only read/write data in a single database. They may, however, read/write data in different tables within that database.

## Locking Read-Write Transactions

Locking transactions may be used to atomically read-modify-write data anywhere in a database. This type of transaction is externally consistent.

Clients should attempt to minimize the amount of time a transaction is active. Faster transactions commit with higher probability and cause less contention. Cloud Spanner attempts to keep read locks active as long as the transaction continues to do reads, and the transaction has not been terminated by Commit or Rollback. Long periods of inactivity at the client may cause Cloud Spanner to release a transaction's locks and abort it.

Conceptually, a read-write transaction consists of zero or more reads or SQL statements followed by Commit. At any time before Commit, the client can send a Rollback request to abort the transaction.

### Semantics

Cloud Spanner can commit the transaction if all read locks it acquired are still valid at commit time, and it is able to acquire write locks for all writes. Cloud Spanner can abort the transaction for any reason. If a commit attempt returns `ABORTED`, Cloud Spanner guarantees that the transaction has not modified any user data in Cloud Spanner.

Unless the transaction commits, Cloud Spanner makes no guarantees about how long the transaction's locks were held for. It is an error to use Cloud Spanner locks for any sort of mutual exclusion other than between Cloud Spanner transactions themselves.

### Retrying Aborted Transactions

When a transaction aborts, the application can choose to retry the whole transaction again. To maximize the chances of successfully committing the retry, the client should execute the retry in the same session as the original attempt. The original session's lock priority increases with each consecutive abort, meaning that each attempt has a slightly better chance of success than the previous.

Under some circumstances (e.g., many transactions attempting to modify the same row(s)), a transaction can abort many times in a short period before successfully committing. Thus, it is not a good idea to cap the number of retries a transaction can attempt; instead, it is better to limit the total amount of wall time spent retrying.

### Idle Transactions

A transaction is considered idle if it has no outstanding reads or SQL queries and has not started a read or SQL query within the last 10 seconds. Idle transactions can be aborted by Cloud Spanner so that they don't hold on to locks indefinitely. In that case, the commit will fail with error `ABORTED`.

If this behavior is undesirable, periodically executing a simple SQL query in the transaction (e.g., `SELECT 1`) prevents the transaction from becoming idle.

## Snapshot Read-Only Transactions

Snapshot read-only transactions provides a simpler method than locking read-write transactions for doing several consistent reads. However, this type of transaction does not support writes.

Snapshot transactions do not take locks. Instead, they work by choosing a Cloud Spanner timestamp, then executing all reads at that timestamp. Since they do not acquire locks, they do not block concurrent read-write transactions.

Unlike locking read-write transactions, snapshot read-only transactions never abort. They can fail if the chosen read timestamp is garbage collected; however, the default garbage collection policy is generous enough that most applications do not need to worry about this in practice.

Snapshot read-only transactions do not need to call Commit or Rollback (and in fact are not permitted to do so).

To execute a snapshot transaction, the client specifies a timestamp bound, which tells Cloud Spanner how to choose a read timestamp.

The types of timestamp bound are:

  • Strong (the default).
  • Bounded staleness.
  • Exact staleness.

If the Cloud Spanner database to be read is geographically distributed, stale read-only transactions can execute more quickly than strong or read-write transaction, because they are able to execute far from the leader replica.

Each type of timestamp bound is discussed in detail below.

### Strong

Strong reads are guaranteed to see the effects of all transactions that have committed before the start of the read. Furthermore, all rows yielded by a single read are consistent with each other -- if any part of the read observes a transaction, all parts of the read see the transaction.

Strong reads are not repeatable: two consecutive strong read-only transactions might return inconsistent results if there are concurrent writes. If consistency across reads is required, the reads should be executed within a transaction or at an exact read timestamp.

See TransactionOptions.ReadOnly.strong.

### Exact Staleness

These timestamp bounds execute reads at a user-specified timestamp. Reads at a timestamp are guaranteed to see a consistent prefix of the global transaction history: they observe modifications done by all transactions with a commit timestamp <= the read timestamp, and observe none of the modifications done by transactions with a larger commit timestamp. They will block until all conflicting transactions that may be assigned commit timestamps <= the read timestamp have finished.

The timestamp can either be expressed as an absolute Cloud Spanner commit timestamp or a staleness relative to the current time.

These modes do not require a "negotiation phase" to pick a timestamp. As a result, they execute slightly faster than the equivalent boundedly stale concurrency modes. On the other hand, boundedly stale reads usually return fresher results.

See TransactionOptions.ReadOnly.read_timestamp and TransactionOptions.ReadOnly.exact_staleness.

### Bounded Staleness

Bounded staleness modes allow Cloud Spanner to pick the read timestamp, subject to a user-provided staleness bound. Cloud Spanner chooses the newest timestamp within the staleness bound that allows execution of the reads at the closest available replica without blocking.

All rows yielded are consistent with each other -- if any part of the read observes a transaction, all parts of the read see the transaction. Boundedly stale reads are not repeatable: two stale reads, even if they use the same staleness bound, can execute at different timestamps and thus return inconsistent results.

Boundedly stale reads execute in two phases: the first phase negotiates a timestamp among all replicas needed to serve the read. In the second phase, reads are executed at the negotiated timestamp.

As a result of the two phase execution, bounded staleness reads are usually a little slower than comparable exact staleness reads. However, they are typically able to return fresher results, and are more likely to execute at the closest replica.

Because the timestamp negotiation requires up-front knowledge of which rows will be read, it can only be used with single-use read-only transactions.

See TransactionOptions.ReadOnly.max_staleness and TransactionOptions.ReadOnly.min_read_timestamp.

### Old Read Timestamps and Garbage Collection

Cloud Spanner continuously garbage collects deleted and overwritten data in the background to reclaim storage space. This process is known as "version GC". By default, version GC reclaims versions after they are one hour old. Because of this, Cloud Spanner cannot perform reads at read timestamps more than one hour in the past. This restriction also applies to in-progress reads and/or SQL queries whose timestamp become too old while executing. Reads and SQL queries with too-old read timestamps fail with the error `FAILED_PRECONDITION`.

## Partitioned DML Transactions

Partitioned DML transactions are used to execute DML statements with a different execution strategy that provides different, and often better, scalability properties for large, table-wide operations than DML in a ReadWrite transaction. Smaller scoped statements, such as an OLTP workload, should prefer using ReadWrite transactions.

Partitioned DML partitions the keyspace and runs the DML statement on each partition in separate, internal transactions. These transactions commit automatically when complete, and run independently from one another.

To reduce lock contention, this execution strategy only acquires read locks on rows that match the WHERE clause of the statement. Additionally, the smaller per-partition transactions hold locks for less time.

That said, Partitioned DML is not a drop-in replacement for standard DML used in ReadWrite transactions.

  • The DML statement must be fully-partitionable. Specifically, the

statement 

must be expressible as the union of many statements which each

access only 

  a single row of the table.

- The statement is not applied atomically to all rows of the table.

Rather, 

the statement is applied atomically to partitions of the table,

in 

independent transactions. Secondary index rows are updated

atomically 

  with the base table rows.

- Partitioned DML does not guarantee exactly-once execution

semantics 

against a partition. The statement will be applied at least once

to each 

partition. It is strongly recommended that the DML statement

should be 

idempotent to avoid unexpected results. For instance, it is

potentially 

dangerous to run a statement such as
`UPDATE table SET column = column + 1` as it could be run multiple

times 

  against some rows.

- The partitions are committed automatically - there is no support

for 

Commit or Rollback. If the call returns an error, or if the client

issuing 

the ExecuteSql call dies, it is possible that some rows had the

statement 

executed on them successfully. It is also possible that statement

was 

  never executed against other rows.

- Partitioned DML transactions may only contain the execution of a

single 

  DML statement via ExecuteSql or ExecuteStreamingSql.

- If any error is encountered during the execution of the

partitioned DML 

operation (for instance, a UNIQUE INDEX violation, division by

zero, or a 

value that cannot be stored due to schema constraints), then the
operation is stopped at that point and an error is returned. It

is 

possible that at this point, some partitions have been committed

(or even 

committed multiple times), and other partitions have not been run

at all.

Given the above, Partitioned DML is good fit for large, database-wide, operations that are idempotent, such as deleting old rows from a very large table.

UpdateDatabaseDdlRequest: Enqueues the given DDL statements to be applied, in order but not necessarily all at once, to the database schema at some point (or points) in the future. The server checks that the statements are executable (syntactically valid, name tables that exist, etc.) before enqueueing them, but they may still fail upon later execution (e.g., if a statement from another batch of statements is applied first and it conflicts in some way, or if there is some data-related problem like a `NULL` value in a column to which `NOT NULL` would be added). If a statement fails, all subsequent statements in the batch are automatically cancelled.

Each batch of statements is assigned a name which can be used with the Operations API to monitor progress. See the operation_id field for more details.
