Interface CleanupTransaction

All Superinterfaces:
IndexTransaction
public interface CleanupTransaction extends IndexTransaction
Performs garbage collection of index entries during a cleanup. Notifies registered indexers of each partition being removed and Compaction and Cleanup are somewhat simpler than dealing with incoming writes, being only concerned with cleaning up stale index entries. When multiple versions of a row are compacted, the CleanupTransaction is notified of the versions being merged, which it diffs against the merge result and forwards to the registered Index.Indexer instances when on commit. Instances are currently scoped to a single row within a partition, but this could be improved to batch process multiple rows within a single partition.
