	// was indexed.
	OnIndexSuccess(blockStart xtime.UnixNano)

	// OnIndexFinalize is executed when the index no longer holds any references
	// to the provided resources. It can be used to cleanup any resources held
	// during the course of indexing. `blockStart` is the startTime of the index

	// for the provided blockStart. It only allows a single index attempt at a time
	// for a single entry.
	// NB(prateek): NeedsIndexUpdate is a CAS, i.e. when this method returns true, it
	// also sets state on the entry to indicate that a write for the given blockStart
	// is going to be sent to the index, and other go routines should not attempt the
	// same write. Callers are expected to ensure they follow this guideline.
	// Further, every call to NeedsIndexUpdate which returns true needs to have a corresponding

	// ReconciledOnIndexSeries attempts to retrieve the most recent index entry from the

	// returns a cleanup function to run once finished using the reconciled entry and

type QueryDocIterator added in v1.2.0

type QueryDocIterator interface {
	Iterator

	// Done returns true if iterator is done and Next will return false on the next call. On the first call this will
	// always return false and Next may still return false for an empty iterator. Callers still need to check for an

	// worker.
	Done() bool
}

QueryDocIterator is an Iterator for all documents returned for a query. See Iterator for more details.
