Types

type BatchWrite 

type BatchWrite struct {
	// Used by the commitlog. If this is false, the commitlog should not write
	// the series at this index.
	SkipWrite bool
	// PendingIndex returns whether a write has a pending index.
	PendingIndex bool
	// Used by the commitlog (series needed to be updated by the shard
	// object first, cannot use the Series provided by the caller as it
	// is missing important fields like Tags.)
	Write Write
	// EncodedTags is used by the commit log, but also held onto as a reference
	// here so that it can be returned to the pool after the write to commit log
	// completes (since the Write.Series gets overwritten in SetOutcome so can't
	// use the reference there for returning to the pool).
	EncodedTags ts.EncodedTags
	// Used to help the caller tie errors back to an index in their
	// own collection.
	OriginalIndex int
	// Used by the commitlog.
	Err error
}

BatchWrite represents a write that was added to the BatchWriter.

type BatchWriter 

type BatchWriter interface {
	Add(
		originalIndex int,
		id ident.ID,
