type AdminMergeRequest 

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

An AdminMergeRequest is arguments 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 AdminSplitRequest 

type AdminSplitRequest struct {
	RequestHeader    `protobuf:"bytes,1,opt,name=header,embedded=header" json:"header"`
	SplitKey         Key    `protobuf:"bytes,2,opt,name=split_key,customtype=Key" json:"split_key"`
	XXX_unrecognized []byte `json:"-"`
}

An AdminSplitRequest is arguments 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.

type Combinable 

type Combinable interface {
	Combine(Response)
}

Combinable is implemented by response types whose corresponding requests may cross range boundaries, such as Scan or DeleteRange. 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 struct {
	ActualValue      *Value `protobuf:"bytes,1,opt,name=actual_value" json:"actual_value,omitempty"`
	XXX_unrecognized []byte `json:"-"`
}

	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 arguments 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 InternalPushTxnRequest is arguments to the InternalPushTxn() 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.

An InternalRangeLookupRequest is arguments to the InternalRangeLookup() method. It specifies the key for which the containing range is being requested, and the maximum number of total range descriptors that should be returned, if there are additional consecutive addressable ranges. Specify max_ranges > 1 to pre-fill the range descriptor cache.

	// Holds a wall time, expressed as a unix epoch time in nanoseconds. This
	// represents the earliest possible timestamp for a sample within the

}

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.

InternalTruncateLogRequest 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.

Key is a custom type for a byte string in proto messages which refer to Cockroach keys.

func MakeKey 

func MakeKey(keys ...Key) Key

MakeKey makes a new key which is the concatenation of the given inputs, in order.

func (Key) Compare 

func (k Key) Compare(b interval.Comparable) int

Compare implements the llrb.Comparable interface for tree nodes.

func (Key) Equal 

func (k Key) Equal(l Key) bool

Equal returns whether two keys are identical.

func (Key) Format 

func (k Key) Format(f fmt.State, verb rune)

Format implements the fmt.Formatter interface.

func (Key) Less 

func (k Key) Less(l Key) bool

Less implements the util.Ordered interface.

func (Key) Marshal 

func (k Key) Marshal() ([]byte, error)

Marshal implements the gogoproto Marshaler interface.

func (*Key) MarshalTo 

func (k *Key) MarshalTo(data []byte) (int, error)

MarshalTo is required for gogoproto's mashaller.

func (Key) Next 

func (k Key) Next() Key

Next returns the next key in lexicographic sort order.

func (Key) PrefixEnd 

func (k Key) PrefixEnd() Key

PrefixEnd determines the end key given key as a prefix, that is the key that sorts precisely behind all keys starting with prefix: "1" is added to the final byte and the carry propagated. The special cases of nil and KeyMin always returns KeyMax.

func (Key) Size 

func (k Key) Size() int

Size is required for gogoproto's marshaller.

func (Key) String 

func (k Key) String() string

String returns a string-formatted version of the key.

func (*Key) Unmarshal 

func (k *Key) Unmarshal(bytes []byte) error

Unmarshal implements the gogoproto Unmarshaler interface. It should never set k to be nil as a nil value should never have unmarshal called for it. Futhermore, appending a 0 length byte slice to a 0 length byte slice will produce a nil byte slice, which can cause problems when unmarshalling the engine.MinKey of "".

func (*Key) UnmarshalJSON

UnmarshalJSON implements the json Unmarshaler interface.

type KeyGetter 

type KeyGetter interface {

KeyGetter is a hack to allow Compare() to work for the batch update structs which wrap RawKeyValue. TODO(petermattis): Is there somehow a better way to do this? 

It kept dying at runtime in the previous version of Compare
which type cast the llrb.Comparable to a RawKeyValue. Because
I'm wrapping a RawKeyValue with BatchDelete/BatchPut/BatchMerge.

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.

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.

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 Range.InternalPushTxn).

func (*Value) Verify 

func (v *Value) Verify(key []byte) error

Verify verifies the value's Checksum matches a newly-computed checksum of the value's contents. If the value's Checksum is not set the verification is a noop. It also ensures that both Bytes and Integer are not both set.

type WriteIntentError 

type WriteIntentError struct {
	Intents          []WriteIntentError_Intent `protobuf:"bytes,1,rep,name=intents" json:"intents"`
	Resolved         bool                      `protobuf:"varint,2,opt,name=resolved" json:"resolved"`
	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.
