> Key: CASSANDRA-13746

> Project: Cassandra
> Issue Type: Improvement
> Components: Compaction, Core
> Reporter: Richard Andersen
> Priority: Minor

> Currently anti-compaction has two log event forms. They are:
> INFO [CompactionExecutor:659] 2016-12-11 03:09:46,553
> CompactionManager.java:511 - Starting anticompaction for

> INFO [AntiCompactionExecutor:12] 2017-07-02 09:05:42,471
> CompactionManager.java:1242 - Anticompaction completed successfully,
> anticompacted from 0 to 1 sstable(s).
> It would be nice to have the following:
> 1) the actual keyspace and table name instead of parsing the SSTable file name
> 2) IO rate and duration (like in compaction log messages, e.g., 1,028ms =
> 0.057896MB/s)
> 3) Partition merge counts (like in compaction log messages, e.g., {1:1456,
> })
> This information can be important for creating event timelines and aiding in
> performance troubleshooting.
