Modifier and Type	Interface and Description
static class	CompactDeletionFile.GeneratedDeletionFile A generated files implementation of CompactDeletionFile.
static class	CompactDeletionFile.LazyCompactDeletionFile A lazy generation implementation of CompactDeletionFile.

Method Summary

Modifier and Type	Method and Description
void	clean()
static CompactDeletionFile	generateFiles(DeletionVectorsMaintainer maintainer) Used by async compaction, when compaction task is completed, deletions file will be generated immediately, so when updateCompactResult, we need to merge old deletion files (just delete them).
Optional<IndexFileMeta>	getOrCompute()
static CompactDeletionFile	lazyGeneration(DeletionVectorsMaintainer maintainer) For sync compaction, only create deletion files when prepareCommit.
CompactDeletionFile	mergeOldFile(CompactDeletionFile old)
