Documentation ¶
Overview ¶
Package bigtable is an API to Google Cloud Bigtable.
See https://cloud.google.com/bigtable/docs/ for general product documentation.
See https://godoc.org/cloud.google.com/go for authentication, timeouts, connection pooling and similar aspects of this package.
Reading ¶
The principal way to read from a Bigtable is to use the ReadRows method on *Table. A RowRange specifies a contiguous portion of a table. A Filter may be provided through RowFilter to limit or transform the data that is returned.
tbl := client.Open("mytable") // Read all the rows starting with "com.google.", but only fetch the columns // in the "links" family. rr := bigtable.PrefixRange("com.google.") err := tbl.ReadRows(ctx, rr, func(r Row) bool { // TODO: do something with r. return true // Keep going. }, bigtable.RowFilter(bigtable.FamilyFilter("links"))) if err != nil { // TODO: handle err. }
To read a single row, use the ReadRow helper method:
r, err := tbl.ReadRow(ctx, "com.google.cloud") // "com.google.cloud" is the entire row key if err != nil { // TODO: handle err. } // TODO: use r.
Writing ¶
This API exposes two distinct forms of writing to a Bigtable: a Mutation and a ReadModifyWrite. The former expresses idempotent operations. The latter expresses non-idempotent operations and returns the new values of updated cells. These operations are performed by creating a Mutation or ReadModifyWrite (with NewMutation or NewReadModifyWrite), building up one or more operations on that, and then using the Apply or ApplyReadModifyWrite methods on a Table.
For instance, to set a couple of cells in a table:
tbl := client.Open("mytable") mut := bigtable.NewMutation() // To use numeric values that will later be incremented, // they need to be big-endian encoded as 64-bit integers. buf := new(bytes.Buffer) initialLinkCount := 1 // The initial number of links. if err := binary.Write(buf, binary.BigEndian, initialLinkCount); err != nil { // TODO: handle err. } mut.Set("links", "maps.google.com", bigtable.Now(), buf.Bytes()) mut.Set("links", "golang.org", bigtable.Now(), buf.Bytes()) err := tbl.Apply(ctx, "com.google.cloud", mut) if err != nil { // TODO: handle err. }
To increment an encoded value in one cell:
tbl := client.Open("mytable") rmw := bigtable.NewReadModifyWrite() rmw.Increment("links", "golang.org", 12) // add 12 to the cell in column "links:golang.org" r, err := tbl.ApplyReadModifyWrite(ctx, "com.google.cloud", rmw) if err != nil { // TODO: handle err. } // TODO: use r.
Retries ¶
If a read or write operation encounters a transient error it will be retried until a successful response, an unretryable error or the context deadline is reached. Non-idempotent writes (where the timestamp is set to ServerTime) will not be retried. In the case of ReadRows, retried calls will not re-scan rows that have already been processed.

Apply mutates a row atomically. A mutation must contain at least one operation and at most 100000 operations.
func (*Table) ApplyBulk ¶
func (t *Table) ApplyBulk(ctx context.Context, rowKeys []string, muts []*Mutation, opts ...ApplyOption) (errs []error, err error)
ApplyBulk applies multiple Mutations, up to a maximum of 100,000. Each mutation is individually applied atomically, but the set of mutations may be applied in any order.
Two types of failures may occur. If the entire process fails, (nil, err) will be returned. If specific mutations fail to apply, ([]err, nil) will be returned, and the errors will correspond to the relevant rowKeys/muts arguments.
Conditional mutations cannot be applied in bulk and providing one will result in an error.
func (*Table) ApplyReadModifyWrite ¶
func (t *Table) ApplyReadModifyWrite(ctx context.Context, row string, m *ReadModifyWrite) (Row, error)
ApplyReadModifyWrite applies a ReadModifyWrite to a specific row. It returns the newly written cells.
func (*Table) ReadRow ¶
ReadRow is a convenience implementation of a single-row reader. A missing row will return nil for both Row and error.
func (*Table) ReadRows ¶
func (t *Table) ReadRows(ctx context.Context, arg RowSet, f func(Row) bool, opts ...ReadOption) (err error)
ReadRows reads rows from a table. f is called for each row. If f returns false, the stream is shut down and ReadRows returns. f owns its argument, and f is called serially in order by row key. f will be executed in the same Go routine as the caller.
By default, the yielded rows will contain all values in all cells. Use RowFilter to limit the cells returned.
func (*Table) SampleRowKeys ¶
SampleRowKeys returns a sample of row keys in the table. The returned row keys will delimit contiguous sections of the table of approximately equal size, which can be used to break up the data for distributed tasks like mapreduces.
type TableAPI ¶ added in v1.23.0
type TableAPI interface { ReadRows(ctx context.Context, arg RowSet, f func(Row) bool, opts ...ReadOption) error ReadRow(ctx context.Context, row string, opts ...ReadOption) (Row, error) Apply(ctx context.Context, row string, m *Mutation, opts ...ApplyOption) error ApplyBulk(ctx context.Context, rowKeys []string, muts []*Mutation, opts ...ApplyOption) ([]error, error) SampleRowKeys(ctx context.Context) ([]string, error) ApplyReadModifyWrite(ctx context.Context, row string, m *ReadModifyWrite) (Row, error) }
TableAPI interface allows existing data APIs to be applied to either an authorized view or a table.
type TableAutomatedBackupConfig ¶ added in v1.24.0
type TableAutomatedBackupConfig interface {
// contains filtered or unexported methods
}
TableAutomatedBackupConfig generalizes automated backup configurations. Currently, the only supported type of automated backup configuration is TableAutomatedBackupPolicy.
type TableAutomatedBackupPolicy ¶ added in v1.24.0
type TableAutomatedBackupPolicy struct { // How long the automated backups should be retained. The only // supported value at this time is 3 days. RetentionPeriod optional.Duration // How frequently automated backups should occur. The only // supported value at this time is 24 hours. Frequency optional.Duration }
TableAutomatedBackupPolicy defines an automated backup policy for a table. Use nil TableAutomatedBackupPolicy to disable Automated Backups on a table. Use nil for a specific field to ignore that field when updating the policy on a table.
type TableConf ¶
type TableConf struct { TableID string SplitKeys []string // DEPRECATED: Use ColumnFamilies instead. // Families is a map from family name to GCPolicy. // Only one of Families or ColumnFamilies may be set. Families map[string]GCPolicy // ColumnFamilies is a map from family name to family configuration. // Only one of Families or ColumnFamilies may be set. ColumnFamilies map[string]Family // DeletionProtection can be none, protected or unprotected // set to protected to make the table protected against data loss DeletionProtection DeletionProtection ChangeStreamRetention ChangeStreamRetention // Configure an automated backup policy for the table AutomatedBackupConfig TableAutomatedBackupConfig }
TableConf contains all the information necessary to create a table with column families.
type TableInfo ¶
type TableInfo struct { // DEPRECATED - This field is deprecated. Please use FamilyInfos instead. Families []string FamilyInfos []FamilyInfo // DeletionProtection indicates whether the table is protected against data loss // DeletionProtection could be None depending on the table view // for example when using NAME_ONLY, the response does not contain DeletionProtection and the value should be None DeletionProtection DeletionProtection ChangeStreamRetention ChangeStreamRetention AutomatedBackupConfig TableAutomatedBackupConfig }
TableInfo represents information about a table.
type Timestamp ¶
type Timestamp int64
Timestamp is in units of microseconds since 1 January 1970.
const ServerTime Timestamp = -1
ServerTime is a specific Timestamp that may be passed to (*Mutation).Set. It indicates that the server's timestamp should be used.
func Now ¶
func Now() Timestamp
Now returns the Timestamp representation of the current time on the client.
func (Timestamp) TruncateToMilliseconds ¶
TruncateToMilliseconds truncates a Timestamp to millisecond granularity, which is currently the only granularity supported.
type Type ¶ added in v1.22.0
type Type interface {
// contains filtered or unexported methods
}
Type wraps the protobuf representation of a type. See the protobuf definition for more details on types.
type UnionGCPolicy ¶ added in v1.16.0
type UnionGCPolicy struct { // List of children policy in the union Children []GCPolicy }
UnionGCPolicy with list of children
func (UnionGCPolicy) String ¶ added in v1.16.0
func (up UnionGCPolicy) String() string
type UpdateAuthorizedViewConf ¶ added in v1.23.0
type UpdateAuthorizedViewConf struct { AuthorizedViewConf AuthorizedViewConf IgnoreWarnings bool }
UpdateAuthorizedViewConf contains all the information necessary to update or partial update an authorized view.
type UpdateInstanceResults ¶ added in v1.1.0
type UpdateInstanceResults struct { InstanceUpdated bool CreatedClusters []string DeletedClusters []string UpdatedClusters []string }
UpdateInstanceResults contains information about the changes made after invoking UpdateInstanceAndSyncClusters.
func UpdateInstanceAndSyncClusters ¶ added in v1.1.0
func UpdateInstanceAndSyncClusters(ctx context.Context, iac *InstanceAdminClient, conf *InstanceWithClustersConfig) (*UpdateInstanceResults, error)
UpdateInstanceAndSyncClusters updates an instance and its clusters, and will synchronize the clusters in the instance with the provided clusters, creating and deleting them as necessary. The provided InstanceWithClustersConfig is used as follows:
- InstanceID is required
- DisplayName and InstanceType are updated only if they are not empty
- ClusterID is required for any provided cluster
- Any cluster present in conf.Clusters but not part of the instance will be created using CreateCluster and the given ClusterConfig.
- Any cluster missing from conf.Clusters but present in the instance will be removed from the instance using DeleteCluster.
- Any cluster in conf.Clusters that also exists in the instance will be updated either to contain the provided number of nodes or to use the provided autoscaling config. If both the number of nodes and autoscaling are configured, autoscaling takes precedence. If the number of nodes is zero and autoscaling is not provided in InstanceWithClustersConfig, the cluster is not updated.
This method may return an error after partially succeeding, for example if the instance is updated but a cluster update fails. If an error is returned, InstanceInfo and Clusters may be called to determine the current state. The return UpdateInstanceResults will describe the work done by the method, whether partial or complete.
func (*UpdateInstanceResults) String ¶ added in v1.1.0
func (r *UpdateInstanceResults) String() string
