SEQ_ID

public static final Comparator<StoreFile> SEQ_ID

Comparator that compares based on the Sequence Ids of the the StoreFiles. Bulk loads that did not request a seq ID are given a seq id of -1; thus, they are placed before all non- bulk loads, and bulk loads with sequence Id. Among these files, the size is used to determine the ordering, then bulkLoadTime. If there are ties, the path name is used as a tie-breaker.

SEQ_ID_MAX_TIMESTAMP

public static final Comparator<StoreFile> SEQ_ID_MAX_TIMESTAMP

Comparator for time-aware compaction. SeqId is still the first ordering criterion to maintain MVCC.
