CompactionTransaction (apache-cassandra API)

All Superinterfaces:

IndexTransaction
```
public interface CompactionTransaction
extends IndexTransaction
```
Performs garbage collection of stale index entries during a regular compaction. A CompactionTransaction is concerned with cleaning up stale index entries. When multiple versions of a row are compacted, the CompactionTransaction is notified of the versions being merged, which it diffs against the merge result. 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.
