Functions

func BytesNext 

func BytesNext(b []byte) []byte

BytesNext returns the next possible byte slice, using the extra capacity of the provided slice if possible, and if not, appending an \x00.

func ConsultsTimestampCache 

func ConsultsTimestampCache(args Request) bool

ConsultsTimestampCache returns whether the command must consult the timestamp cache to determine whether a mutation is safe at a proposed timestamp or needs to move to a higher timestamp to avoid re-writing history.

func ErrorUnexpectedlySet 

func ErrorUnexpectedlySet(culprit, response interface{}) string

ErrorUnexpectedlySet creates a string to panic with when a response (typically a roachpb.BatchResponse) unexpectedly has Error set in its response header.

func IsRange 

func IsRange(args Request) bool

IsRange returns true if the command is range-based and must include a start and an end key.

func IsReadOnly 

func IsReadOnly(args Request) bool

IsReadOnly returns true iff the request is read-only.

func IsTransactionWrite 

func IsTransactionWrite(args Request) bool

IsTransactionWrite returns true if the request produces write intents when used within a transaction.

func MakePriority 

func MakePriority(userPriority UserPriority) int32

MakePriority generates a random priority value, biased by the specified userPriority. If userPriority=100, the random priority will be 100x more likely to be greater than if userPriority=1. If userPriority = 0.1, the random priority will be 1/10th as likely to be greater than if userPriority=1. Balance is achieved when userPriority=1, in which case the priority chosen is unbiased.

If userPriority is less than or equal to MinUserPriority, returns MinTxnPriority; if greater than or equal to MaxUserPriority, returns MaxTxnPriority.

func RegisterExternalServer 

func RegisterExternalServer(s *grpc.Server, srv ExternalServer)

func RegisterInternalServer 

func RegisterInternalServer(s *grpc.Server, srv InternalServer)

func TxnIDEqual 

func TxnIDEqual(a, b *uuid.UUID) bool

TxnIDEqual returns whether the transaction IDs are equal.

func UpdatesTimestampCache 

func UpdatesTimestampCache(args Request) bool

UpdatesTimestampCache returns whether the command must update the timestamp cache in order to set a low water mark for the timestamp at which mutations to overlapping key(s) can write such that they don't re-write history.

Types

type AbortCacheEntry 

type AbortCacheEntry struct {
	// The key of the associated transaction.
	Key Key `protobuf:"bytes,1,opt,name=key,casttype=Key" json:"key,omitempty"`
	// The candidate commit timestamp the transaction record held at the time
	// it was aborted.
	Timestamp cockroach_util_hlc.Timestamp `protobuf:"bytes,2,opt,name=timestamp" json:"timestamp"`
	// The priority of the transaction.
	Priority int32 `protobuf:"varint,3,opt,name=priority" json:"priority"`
}

AbortCacheEntry contains information about a transaction which has been aborted. It's written to a range's abort cache if the range may have contained intents of the aborted txn. In the event that the same transaction attempts to read keys it may have written previously, this entry informs the transaction that it has aborted and must start fresh with an updated priority.

type AdminMergeRequest 

type AdminMergeRequest struct {
	Span `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
}

An AdminMergeRequest is the argument to the AdminMerge() method. A merge is performed by calling AdminMerge on the left-hand range of two consecutive ranges (i.e. the range which contains keys which sort first). This range will be the subsuming range and the right hand range will be subsumed. After the merge operation, the subsumed range will no longer exist and the subsuming range will now encompass all keys from its original start key to the end key of the subsumed range. If AdminMerge is called on the final range in the key space, it is a noop.

type AdminScatterRequest 

type AdminScatterRequest struct {
	Span `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
}

AdminScatterRequest is the argument to the AdminScatter() method, which moves replicas and leaseholders for a selection of ranges. Scatter is best-effort; ranges that cannot be moved will include an error detail in the response and won't fail the request.

	SplitKey Key `protobuf:"bytes,2,opt,name=split_key,json=splitKey,casttype=Key" json:"split_key,omitempty"`
}

An AdminSplitRequest is the argument to the AdminSplit() method. The existing range which contains header.key is split by split_key. If split_key is not specified, then this method will determine a split key that is roughly halfway through the range. The existing range is resized to cover only its start key to the split key. The new range created by the split starts at the split key and extends to the original range's end key. If split_key is known, header.key should also be set to split_key.

New range IDs for each of the split range's replica and a new Raft ID are generated by the operation. Split requests are done in the context of a distributed transaction which updates range addressing records, range metadata and finally, provides a commit trigger to update bookkeeping and instantiate the new range on commit.

The new range contains range replicas located on the same stores; no range data is moved during this operation. The split can be thought of as a mostly logical operation, though some other metadata (e.g. sequence cache and range stats must be copied or recomputed).

type BatchRequest 

type BatchRequest struct {
	Header   `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
	Requests []RequestUnion `protobuf:"bytes,2,rep,name=requests" json:"requests"`
}

A BatchRequest contains one or more requests to be executed in parallel, or if applicable (based on write-only commands and range-locality), as a single update.

func (*BatchRequest) Add 

func (ba *BatchRequest) Add(requests ...Request)

Add adds a request to the batch request. It's a convenience method; requests may also be added directly into the slice.

func (*BatchRequest) CreateReply 

func (ba *BatchRequest) CreateReply() *BatchResponse

CreateReply creates replies for each of the contained requests, wrapped in a BatchResponse. The response objects are batch allocated to minimize allocation overhead.

func (*BatchRequest) Descriptor 

func (*BatchRequest) Descriptor() ([]byte, []int)

func (*BatchRequest) GetArg 

func (ba *BatchRequest) GetArg(method Method) (Request, bool)

GetArg returns a request of the given type if one is contained in the Batch. The request returned is the first of its kind, with the exception of EndTransaction, where it examines the very last request only.

func (*BatchRequest) GetPrevLeaseForLeaseRequest 

func (ba *BatchRequest) GetPrevLeaseForLeaseRequest() *Lease

GetPrevLeaseForLeaseRequest returns the previous lease, at the time of proposal, for a request lease or transfer lease request. If the batch does not contain a single lease request, this method will panic.

func (*BatchRequest) GetUser 

func (*BatchRequest) GetUser() string

GetUser implements security.RequestWithUser. KV messages are always sent by the node user.

func (*BatchRequest) IntentSpanIterate 

func (ba *BatchRequest) IntentSpanIterate(br *BatchResponse, fn func(key, endKey Key))

IntentSpanIterate calls the passed method with the key ranges of the transactional writes contained in the batch. Usually the key spans contained in the requests are used, but when a response contains a ResumeSpan the ResumeSpan is subtracted from the request span to provide a more minimal span of keys affected by the request.

func (*BatchRequest) IsAdmin 

func (ba *BatchRequest) IsAdmin() bool

IsAdmin returns true iff the BatchRequest contains an admin request.

func (*BatchRequest) IsLeaseRequest 

func (ba *BatchRequest) IsLeaseRequest() bool

IsLeaseRequest returns whether the batch consists of a single RequestLease request. Note that TransferLease requests return false. RequestLease requests are special because they're the only type of requests a non-lease-holder can propose.

func (*BatchRequest) IsPossibleTransaction 

func (ba *BatchRequest) IsPossibleTransaction() bool

IsPossibleTransaction returns true iff the BatchRequest contains requests that can be part of a transaction.

func (*BatchRequest) IsReadOnly 

func (ba *BatchRequest) IsReadOnly() bool

IsReadOnly returns true if all requests within are read-only.

func (*BatchRequest) IsReverse 

func (ba *BatchRequest) IsReverse() bool

IsReverse returns true iff the BatchRequest contains a reverse request.

func (*BatchRequest) IsSinglePushTxnRequest 

func (ba *BatchRequest) IsSinglePushTxnRequest() bool

IsSinglePushTxnRequest returns true iff the batch contains a single request, and that request is for a PushTxn.

func (*BatchRequest) IsSingleRequest 

func (ba *BatchRequest) IsSingleRequest() bool

IsSingleRequest returns true iff the BatchRequest contains a single request.

func (*BatchRequest) IsSingleSkipLeaseCheckRequest 

func (ba *BatchRequest) IsSingleSkipLeaseCheckRequest() bool

IsSingleSkipLeaseCheckRequest returns true iff the batch contains a single request, and that request has the skipLeaseCheck flag set.

func (*BatchRequest) Reset 

func (m *BatchRequest) Reset()

func (*BatchRequest) SetActiveTimestamp 

func (ba *BatchRequest) SetActiveTimestamp(nowFn func() hlc.Timestamp) error

SetActiveTimestamp sets the correct timestamp at which the request is to be carried out. For transactional requests, ba.Timestamp must be zero initially and it will be set to txn.OrigTimestamp. For non-transactional requests, if no timestamp is specified, nowFn is used to create and set one.

func (*BatchRequest) SetNewRequest 

func (ba *BatchRequest) SetNewRequest()

SetNewRequest increases the internal sequence counter of this batch request. The sequence counter is used for replay and reordering protection. At the Store, a sequence counter less than or equal to the last observed one incurs a transaction restart (if the request is transactional).

func (*BatchRequest) Size 

func (m *BatchRequest) Size() (n int)

func (BatchRequest) Split 

func (ba BatchRequest) Split(canSplitET bool) [][]RequestUnion

Split separates the requests contained in a batch so that each subset of requests can be executed by a Store (without changing order). In particular, Admin requests are always singled out and mutating requests separated from reads. The boolean parameter indicates whether EndTransaction should be special-cased: If false, an EndTransaction request will never be split into a new chunk (otherwise, it is treated according to its flags). This allows sending a whole transaction in a single Batch when addressing a single range.

func (BatchRequest) String 

func (ba BatchRequest) String() string

String gives a brief summary of the contained requests and keys in the batch. TODO(tschottdorf): the key range is useful information, but requires `keys`. See #2198.

func (*BatchRequest) Summary 

func (ba *BatchRequest) Summary() string

Summary prints a short summary of the requests in a batch.

func (*BatchRequest) Unmarshal 

func (m *BatchRequest) Unmarshal(dAtA []byte) error

func (*BatchRequest) UpdateTxn 

func (ba *BatchRequest) UpdateTxn(otherTxn *Transaction)

UpdateTxn updates the batch transaction from the supplied one in a copy-on-write fashion, i.e. without mutating an existing Transaction struct.

type BatchResponse 

type BatchResponse struct {
	BatchResponse_Header `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
	Responses            []ResponseUnion `protobuf:"bytes,2,rep,name=responses" json:"responses"`
}

A BatchResponse contains one or more responses, one per request corresponding to the requests in the matching BatchRequest. The error in the response header is set to the first error from the slice of responses, if applicable.

func (*BatchResponse) Add 

func (br *BatchResponse) Add(reply Response)

Add adds a response to the batch response. It's a convenience method; responses may also be added directly.

func (*BatchResponse) Combine 

func (br *BatchResponse) Combine(otherBatch *BatchResponse) error

Combine implements the Combinable interface. It combines each slot of the given request into the corresponding slot of the base response. The number of slots must be equal and the respective slots must be combinable. On error, the receiver BatchResponse is in an invalid state. TODO(tschottdorf): write tests.

}

HandledRetryableTxnError is an error detail representing a retryable error that has been "handled" by the TxnCoordSender. This error is produced by the TxnCoordSender and is only produced for transactional requests.

It contains the final form of the Transaction proto that should be used on next attempts. After being produced by the TxnCoordSender, this error is handled first by the client.Txn, which uses the Transaction inside to update its state, and then passed along to SQL in a pErr (through the client.Sender() interface).

type InternalTimeSeriesData 

type InternalTimeSeriesData struct {
	// Holds a wall time, expressed as a unix epoch time in nanoseconds. This

	// collection.
	StartTimestampNanos int64 `protobuf:"varint,1,opt,name=start_timestamp_nanos,json=startTimestampNanos" json:"start_timestamp_nanos"`

	// The actual data samples for this metric.
	Samples []InternalTimeSeriesSample `protobuf:"bytes,3,rep,name=samples" json:"samples"`
}

InternalTimeSeriesData is a collection of data samples for some measurable value, where each sample is taken over a uniform time interval.

The collection itself contains a start timestamp (in seconds since the unix epoch) and a sample duration (in milliseconds). Each sample in the collection will contain a positive integer offset that indicates the length of time between the start_timestamp of the collection and the time when the sample began, expressed as an whole number of sample intervals. For example, if the sample duration is 60000 (indicating 1 minute), then a contained sample with an offset value of 5 begins (5*60000ms = 300000ms = 5 minutes) after the start timestamp of this data.

This is meant to be an efficient internal representation of time series data, ensuring that very little redundant data is stored on disk. With this goal in mind, this message does not identify the variable which is actually being measured; that information is expected be encoded in the key where this message is stored.

	// Minimum encountered measurement in this sample.
	Min *float64 `protobuf:"fixed64,9,opt,name=min" json:"min,omitempty"`
}

A InternalTimeSeriesSample represents data gathered from multiple measurements of a variable value over a given period of time. The length of that period of time is stored in an InternalTimeSeriesData message; a sample cannot be interpreted correctly without a start timestamp and sample duration.

Each sample may contain data gathered from multiple measurements of the same variable, as long as all of those measurements occurred within the sample period. The sample stores several aggregated values from these measurements: - The sum of all measured values - A count of all measurements taken - The maximum individual measurement seen - The minimum individual measurement seen

If zero measurements are present in a sample, then it should be omitted entirely from any collection it would be a part of.

If the count of measurements is 1, then max and min fields may be omitted and assumed equal to the sum field.

type Locality 

type Locality struct {

func (*Locality) Descriptor 

func (*Locality) Descriptor() ([]byte, []int)

func (Locality) DiversityScore 

func (l Locality) DiversityScore(other Locality) float64

DiversityScore returns a score comparing the two localities which ranges from 1, meaning completely diverse, to 0 which means not diverse at all (that their localities match). This function ignores the locality tier key names and only considers differences in their values.

All localities are sorted from most global to most local so any localities after any differing values are irrelevant.

While we recommend that all nodes have the same locality keys and same total number of keys, there's nothing wrong with having different locality keys as long as the immediately next keys are all the same for each value. For example: region:USA -> state:NY -> ... region:USA -> state:WA -> ... region:EUR -> country:UK -> ... region:EUR -> country:France -> ... is perfectly fine. This holds true at each level lower as well.

There is also a need to consider the cases where the localities have different lengths. For these cases, we treat the missing key on one side as different.

A PushTxnRequest is arguments to the PushTxn() method. It's sent by readers or writers which have encountered an "intent" laid down by another transaction. The goal is to resolve the conflict. Note that args.Key should be set to the txn ID of args.PusheeTxn, not args.PusherTxn. This RPC is addressed to the range which owns the pushee's txn record. If the pusher is not transactional, it must be set to a Transaction record with only the Priority present.

Resolution is trivial if the txn which owns the intent has either been committed or aborted already. Otherwise, the existing txn can either be aborted (for write/write conflicts), or its commit timestamp can be moved forward (for read/write conflicts). The course of action is determined by the specified push type, and by the owning txn's status and priority.

A RangeLookupRequest is arguments to the RangeLookup() method. A forward lookup request returns a range containing the requested key. A reverse lookup request returns a range containing the previous key of the requested key (e.g., if a requested key is the end key of range R, the reverse lookup request returns R).

RangeLookupRequest also specifies the maximum number of range descriptors that should be returned, if there are additional consecutive addressable ranges. Specify max_ranges > 1 to pre-fill the range descriptor cache. The additional ranges are scanned in the same direction as lookup (forward v.s. reverse).

A RequestUnion contains exactly one of the optional requests. The values added here must match those in ResponseUnion.

WARNING: Do not remove fields from RequestUnion. Instead, remove all non-header fields from the request message and prepend its name with "Deprecated". See DeprecatedVerifyChecksumRequest for an example.

Be cautious about deprecating fields as doing so can lead to inconsistencies between replicas.

	// For a SNAPSHOT transaction however, this is not the case. Intuitively,

	// Using instead its candidate commit timestamp, it wouldn't see a conflict
	// and commit, but this is not the expected outcome {Amount: 2, Price: 15}
	// and we are experiencing the Lost Update Anomaly.
	//
	// Note that in practice, before restarting, txn1 would still lay down an
	// intent (just above the committed value) not with the intent to commit it,

}

A Transaction is a unit of work performed on the database. Cockroach transactions support two isolation levels: snapshot isolation and serializable snapshot isolation. Each Cockroach transaction is assigned a random priority. This priority will be used to decide whether a transaction will be aborted during contention.

If you add fields to Transaction you'll need to update Transaction.Clone. Failure to do so will result in test failures.

func NewPopulatedTransaction 

func NewPopulatedTransaction(r randyData, easy bool) *Transaction

func NewTransaction 

func NewTransaction(
	name string,
	baseKey Key,
	userPriority UserPriority,
	isolation enginepb.IsolationType,
	now hlc.Timestamp,
	maxOffset int64,
) *Transaction

NewTransaction creates a new transaction. The transaction key is composed using the specified baseKey (for locality with data affected by the transaction) and a random ID to guarantee uniqueness. The specified user-level priority is combined with a randomly chosen value to yield a final priority, used to settle write conflicts in a way that avoids starvation of long-running transactions (see Replica.PushTxn).

func PrepareTransactionForRetry 

func PrepareTransactionForRetry(ctx context.Context, pErr *Error, pri UserPriority) Transaction

PrepareTransactionForRetry returns a new Transaction to be used for retrying the original Transaction. Depending on the error, this might return an already-existing Transaction with an incremented epoch, or a completely new Transaction.

The caller should generally check that the error was meant for this Transaction before calling this.

pri is the priority that should be used when giving the restarted transaction the chance to get a higher priority. Not used when the transaction is being aborted.

In case retryErr tells us that a new Transaction needs to be created, isolation and name help initialize this new transaction.

func (Transaction) Clone 

func (t Transaction) Clone() Transaction

Clone creates a copy of the given transaction. The copy is "mostly" deep, but does share pieces of memory with the original such as Key, ID and the keys with the intent spans.

func (Transaction) GetObservedTimestamp 

func (t Transaction) GetObservedTimestamp(nodeID NodeID) (hlc.Timestamp, bool)

GetObservedTimestamp returns the lowest HLC timestamp recorded from the given node's clock during the transaction. The returned boolean is false if no observation about the requested node was found. Otherwise, MaxTimestamp can be lowered to the returned timestamp when reading from nodeID.

func (*Transaction) IsInitialized 

func (t *Transaction) IsInitialized() bool

IsInitialized returns true if the transaction has been initialized.

func (Transaction) LastActive

func (*Transaction) UpdateObservedTimestamp 

func (t *Transaction) UpdateObservedTimestamp(nodeID NodeID, maxTS hlc.Timestamp)

UpdateObservedTimestamp stores a timestamp off a node's clock for future operations in the transaction. When multiple calls are made for a single nodeID, the lowest timestamp prevails.

func (*Transaction) UpgradePriority 

func (t *Transaction) UpgradePriority(minPriority int32)

UpgradePriority sets transaction priority to the maximum of current priority and the specified minPriority. The exception is if the current priority is set to the minimum, in which case the minimum is preserved.

type TransactionAbortedError 

type TransactionAbortedError struct {
}

A TransactionAbortedError indicates that the transaction was aborted by another concurrent transaction. Upon seeing this error, the client is supposed to reset its Transaction proto and try the transaction again.

In contrast with other errors, the Transaction that the client gets in the pErr carrying this ErrorDetail is not supposed to be used by the client, besides checking that the transaction's ID is right.

A TransactionStatusError indicates that the transaction status is incompatible with the requested operation. This might mean the transaction has already been committed. It might also be the case that the request to modify the transaction failed due to a regression in transaction epoch or timestamp, both of which may only monotonically increase.

	// it has not changed when executing this command.
	PrevLease *Lease `protobuf:"bytes,3,opt,name=prev_lease,json=prevLease" json:"prev_lease,omitempty"`
}

A TransferLeaseRequest represents the arguments to the TransferLease() method. It is sent by a replica that currently holds the range lease and wants to transfer it away.

Like a RequestLeaseRequest, this request has the effect of instituting a new lease. The difference is that the new lease is allowed to overlap the existing one. It is a separate request because the RequestLeaseRequest is special - it's not subject to the same replay protection restrictions as other requests, instead being protected from replays by the fact that leases are not generally allowed to overlap. The TransferLeaseRequest is not special in this respect (for example, the proposer of this command is checked to have been holding the lease when the proposal was made).

}

TruncateLogRequest is used to remove a prefix of the raft log. While there is no requirement for correctness that the raft log truncation be synchronized across replicas, it is nice to preserve the property that all replicas of a range are as close to identical as possible. The raft leader can also inform decisions about the cutoff point with its knowledge of the replicas' acknowledgment status.

}

UnhandledRetryableError tells the recipient that a KV request must be retried. In case the request was transactional, the whole transaction needs to be retried. This is returned generally as a result of a transaction conflict.

This error is generated by pErr.GoError() in case of a retryable error (other than HandledRetryableTxnError). For transactional requests, the TxnCoordSender handles retryable pErrs and transform them into HandledRetryableTxnError. So, for transactional requests, only DistSQL is supposed to see this error (as it doesn't go through TxnCoordSender). For non-transactional requests, this error will be observed by layers above the TxnCoordSender.

	// Timestamp of value.
	Timestamp cockroach_util_hlc.Timestamp `protobuf:"bytes,2,opt,name=timestamp" json:"timestamp"`
}

Value specifies the value at a key. Multiple values at the same key are supported based on timestamp. The data stored within a value is typed (ValueType) and custom encoded into the raw_bytes field. A custom encoding is used instead of separate proto fields to avoid proto overhead and to avoid unnecessary encoding and decoding as the value gets read from disk and passed through the network. The format is: 

<4-byte-checksum><1-byte-tag><encoded-data>

A CRC-32-IEEE checksum is computed from the associated key, tag and encoded data, in that order.

TODO(peter): Is a 4-byte checksum overkill when most (all?) values will be less than 64KB?

ValueType defines a set of type constants placed in the "tag" field of Value messages. These are defined as a protocol buffer enumeration so that they can be used portably between our Go and C code. The tags are used by the RocksDB Merge Operator to perform specialized merges. 

const (
	// This is a subset of the SQL column type values, representing the underlying
	// storage for various types. The DELIMITED_foo entries each represent a foo
	// variant that self-delimits length.

	ValueType_NULL              ValueType = 7
	ValueType_INT               ValueType = 1
	ValueType_FLOAT             ValueType = 2
	ValueType_BYTES             ValueType = 3
	ValueType_DELIMITED_BYTES   ValueType = 8
	ValueType_TIME              ValueType = 4
	ValueType_DECIMAL           ValueType = 5
	ValueType_DELIMITED_DECIMAL ValueType = 9
	ValueType_DURATION          ValueType = 6
	// TUPLE represents a DTuple, encoded as repeated pairs of varint field number
	// followed by a value encoded Datum.
	ValueType_TUPLE ValueType = 10
	// TIMESERIES is applied to values which contain InternalTimeSeriesData.
	ValueType_TIMESERIES ValueType = 100

type WriteBatchRequest 

type WriteBatchRequest struct {
	Span `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
	// The span of keys encoded in data, duplicated because the header span can
	// be modified by DistSender and we use this one to fail fast.
	DataSpan Span `protobuf:"bytes,2,opt,name=data_span,json=dataSpan" json:"data_span"`
	// A BatchRepr, the serialized form of a RocksDB Batch.
	Data []byte `protobuf:"bytes,3,opt,name=data" json:"data,omitempty"`
}

WriteBatchRequest is arguments to the WriteBatch() method, to apply the operations encoded in a BatchRepr.

type WriteIntentError 

type WriteIntentError struct {
	Intents []Intent `protobuf:"bytes,1,rep,name=intents" json:"intents"`
}

A WriteIntentError indicates that one or more write intent belonging to another transaction were encountered leading to a read/write or write/write conflict. The keys at which the intent was encountered are set, as are the txn records for the intents' transactions.
