Expand description

Policy thresholds used to decide when a piece-table document should be compacted.

Fields§

§min_total_bytes: usize

Minimum document size before compaction is considered worthwhile.

§min_piece_count: usize

Minimum piece count before broader compaction is considered.

§small_piece_threshold_bytes: usize

Pieces at or below this size contribute to fragmentation ratio.

§max_average_piece_bytes: usize

Maximum average piece size allowed for deferred compaction recommendations.

§min_fragmentation_ratio: f64

Minimum ratio of small pieces required before deferred compaction is recommended.

§forced_piece_count: usize

Hard piece-count threshold for forced compaction recommendations.

§forced_fragmentation_ratio: f64

Hard fragmentation ratio threshold for forced compaction recommendations.
