	// 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
	// block for which the write was attempted.
	OnIndexFinalize(blockStart xtime.UnixNano)

	// OnIndexPrepare prepares the Entry to be handed off to the indexing sub-system.
	// NB(prateek): we retain the ref count on the entry while the indexing is pending,
	// the callback executed on the entry once the indexing is completed releases this
	// reference.
	OnIndexPrepare(blockStart xtime.UnixNano)

	// NeedsIndexUpdate returns a bool to indicate if the Entry needs to be indexed
	// 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
	// OnIndexFinalze() call. This is required for correct lifecycle maintenance.
	NeedsIndexUpdate(indexBlockStartForWrite xtime.UnixNano) bool

	// IfAlreadyIndexedMarkIndexSuccessAndFinalize checks if the blockStart has been indexed.
	// If indexed, it will be marked as such and finalized, and then return true. Otherwise false.
	IfAlreadyIndexedMarkIndexSuccessAndFinalize(
		blockStart xtime.UnixNano,

	IndexedForBlockStart(blockStart xtime.UnixNano) bool

	// IndexedRange returns minimum and maximum blockStart values covered by index entry.
	// The range is inclusive. Note that there may be uncovered gaps within the range.
	// Returns (0, 0) for an empty range.
	IndexedRange() (xtime.UnixNano, xtime.UnixNano)

	// ReconciledOnIndexSeries attempts to retrieve the most recent index entry from the
	// shard if the entry this method was called on was never inserted there. If there
	// is an error during retrieval, simply returns the current entry. Additionally,
	// returns a cleanup function to run once finished using the reconciled entry and
	// a boolean value indicating whether the result came from reconciliation or not.
	// Cleanup function must be called once done with the reconciled entry so that
	// reader and writer counts are accurately updated.

type QueryDocIterator added in v1.2.0 

type QueryDocIterator interface {

	// always return false and Next may still return false for an empty iterator. Callers still need to check for an
	// Err after Done returns true.
	// This is used by the index query path to check if there are more docs to process before waiting for an index
	// worker.
	Done() bool
}

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