Tiered merge policy. When the number of segments at a given size tier exceeds a configurable threshold, the smallest segments in that tier are merged into one. Old segments are removed only after the merged segment is fully committed.

SegmentMerger

SegmentMerger(MMapDirectory, IMergePolicy, int, double, HnswBuildConfig?, IMetricsCollector?, bool)

Initialises a merger bound to the given directory.

SegmentMerger(MMapDirectory, int, int, double, HnswBuildConfig?, IMetricsCollector?)

Initialises a merger bound to the given directory with the default tiered policy.

DefaultMergeThreshold

Default merge threshold: when this many segments exist, merge.

DefaultSkipInterval

Default postings skip interval.

DefaultSoftDeleteRetentionSeconds

Default soft-delete retention period in seconds (24 hours).

MaybeMerge(List<SegmentInfo>, ref int)

Checks if a merge is needed and performs it. Returns the updated segment list.

MaybeMerge(List<SegmentInfo>, ref int, IReadOnlySet<string>, int)

Checks if a merge is needed and performs it, excluding segments protected by held snapshots.

MergeAll(List<SegmentInfo>, ref int, int)

Forces a full merge of all given segments into a single new segment, bypassing tier-based merge policy. Used by Compact().

MergeSegmentsFromDirectory(MMapDirectory, List<SegmentInfo>, ref int, IndexWriterConfig, int)

Merges segments from a foreign directory into a single new segment in the target directory. Used by AddIndexes(MMapDirectory).
