Struct tantivy::SearcherGeneration
source · pub struct SearcherGeneration { /* private fields */ }
Expand description
Identifies the searcher generation accessed by a Searcher
.
While this might seem redundant, a SearcherGeneration
contains
both a generation_id
AND a list of (SegmentId, DeleteOpstamp)
.
This is on purpose. This object is used by the Warmer
API.
Having both information makes it possible to identify which
artifact should be refreshed or garbage collected.
Depending on the use case, Warmer
’s implementers can decide to
produce artifacts per:
generation_id
(e.g. some searcher level aggregates)(segment_id, delete_opstamp)
(e.g. segment level aggregates)segment_id
(e.g. for immutable document level information)(generation_id, segment_id)
(e.g. for consistent dynamic column)- …
