Types

type AdminMergeRequest 

type AdminMergeRequest struct {
	RequestHeader    `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
	XXX_unrecognized []byte `json:"-"`
}

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.

	SplitKey         Key    `protobuf:"bytes,2,opt,name=split_key,casttype=Key" json:"split_key,omitempty"`
	XXX_unrecognized []byte `json:"-"`
}

An AdminSplitRequest is the argument to the AdminSplit() method. The existing range which contains RequestHeader.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. response cache and range stats must be copied or recomputed).

type ClientCmdID 

type ClientCmdID struct {
	// Nanoseconds since Unix epoch.
	WallTime         int64  `protobuf:"varint,1,opt,name=wall_time" json:"wall_time"`
	Random           int64  `protobuf:"varint,2,opt,name=random" json:"random"`
	XXX_unrecognized []byte `json:"-"`
}

ClientCmdID provides a unique ID for client commands. Clients which provide ClientCmdID gain operation idempotence. In other words, clients can submit the same command multiple times and always receive the same response. This is common on retries over flaky networks. However, the system imposes a limit on how long idempotence is provided. Retries over an hour old are not guaranteed idempotence and may be executed more than once with potentially different results.

ClientCmdID contains the client's timestamp and a client-generated random number. The client Timestamp is specified in unix nanoseconds and is used for some uniqueness but also to provide a rough ordering of requests, useful for data locality on the server. The Random is specified for additional uniqueness. NOTE: An accurate time signal IS NOT required for correctness.

Combine() allows responses from individual ranges to be aggregated into a single one. It is not expected that Combine() perform any error checking; this should be done by the caller instead.

type ConditionFailedError 

type ConditionFailedError struct {
	ActualValue      *Value `protobuf:"bytes,1,opt,name=actual_value" json:"actual_value,omitempty"`
	XXX_unrecognized []byte `json:"-"`

type ConditionalPutRequest 

type ConditionalPutRequest struct {
	RequestHeader `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
	// The value to put.
	Value Value `protobuf:"bytes,2,opt,name=value" json:"value"`
	// ExpValue.Bytes empty to test for non-existence. Specify as nil
	// to indicate there should be no existing entry. This is different
	// from the expectation that the value exists but is empty.
	ExpValue         *Value `protobuf:"bytes,3,opt,name=exp_value" json:"exp_value,omitempty"`
	XXX_unrecognized []byte `json:"-"`
}

A ConditionalPutRequest is the argument to the ConditionalPut() method.

- Returns true and sets value if ExpValue equals existing value. - If key doesn't exist and ExpValue is nil, sets value. - If key exists, but value is empty and ExpValue is not nil but empty, sets value. - Otherwise, returns error and the actual value of the key in the response.

}

An IncrementRequest is the argument to the Increment() method. It increments the value for key, and returns the new value. If no value exists for a key, incrementing by 0 is not a noop, but will create a zero value. IncrementRequest cannot be called on a key set by Put() or ConditionalPut(). Similarly, Put() and ConditionalPut() cannot be invoked on an incremented key.

	XXX_unrecognized []byte                      `json:"-"`
}

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.

	Min              *float64 `protobuf:"fixed64,9,opt,name=min" json:"min,omitempty"`
	XXX_unrecognized []byte   `json:"-"`
}

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 occured 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.

	RangeLookup      bool   `protobuf:"varint,5,opt,name=range_lookup" json:"range_lookup"`
	XXX_unrecognized []byte `json:"-"`
}

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.Txn, as is usual. This RPC is addressed to the range which owns the pushee's txn record.

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.

func (TimeSeriesData) ToInternal 

func (ts TimeSeriesData) ToInternal(keyDuration int64, sampleDuration int64) (
	[]*InternalTimeSeriesData, error)

ToInternal places the datapoints in a TimeSeriesData message into one or more InternalTimeSeriesData messages. The structure and number of messages returned depends on two variables: a key duration, and a sample duration.

The key duration is an interval length in nanoseconds used to determine how many intervals are grouped into a single InternalTimeSeriesData message.

The sample duration is also an interval length in nanoseconds; it must be less than or equal to the key duration, and must also evenly divide the key duration. Datapoints which fall into the same sample interval will be aggregated together into a single Sample.

Example: Assume the desired result is to aggregate individual datapoints into the same sample if they occurred within the same second; additionally, all samples which occur within the same hour should be stored at the same key location within the same InternalTimeSeriesValue. The sample duration should be 10^9 nanoseconds (value of time.Second), and the key duration should be (3600*10^9) nanoseconds (value of time.Hour).

Note that this method does not accumulate data into individual samples in the case where multiple datapoints fall into the same sample period. Internal data should be merged into the cockroach data store before being read; the engine is responsible for accumulating samples.

The returned slice of InternalTimeSeriesData objects will not be sorted.

For more information on how time series data is stored, see InternalTimeSeriesData and its related structures.

type TimeSeriesQueryAggregator 

type TimeSeriesQueryAggregator int32

TimeSeriesQueryAggregator describes a set of aggregation functions which are applied to data points before returning them as part of a query.

Cockroach does not store data points at full fidelity, instead "downsampling" data points into fixed-length sample periods. The value returned for each sample period is equivalent to applying the supplied aggregator function to the original data points that fell within the sample period.

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. TODO(vivek): Remove parts of Transaction that expose internals.

func NewTransaction 

func NewTransaction(name string, baseKey Key, userPriority int32,
	isolation IsolationType, now 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).

TransactionStatus specifies possible states for a transaction. 

const (
	// PENDING is the default state for a new transaction. Transactions
	// move from PENDING to one of COMMITTED or ABORTED. Mutations made
	// as part of a PENDING transactions are recorded as "intents" in

	XXX_unrecognized []byte      `json:"-"`
}

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.

	XXX_unrecognized []byte `json:"-"`
}

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' acknowledgement status.

	XXX_unrecognized []byte  `json:"-"`
}

Value specifies the value at a key. Multiple values at the same key are supported based on timestamp. Values support the union of two basic types: a "bag o' bytes" generic byte slice and an incrementable int64, for use with the Increment API call.

	XXX_unrecognized []byte   `json:"-"`
}

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. Resolved is set if the intent was successfully resolved, meaning the client may retry the operation immediately. If Resolved is false, the client should back off and retry.
