> Currently, viewing the results of past compactions requires parsing the log and looking at the compaction history system table, which doesn't have information about, for example, flushed sstables not previously compacted.
> This is a proposal to extend the information captured for compaction. Initially, this would be done through a JMX call, but if it proves to be useful and not much overhead, it might be a feature that could be enabled for the compaction strategy all the time.
> Initial log information would include:
> - The compaction strategy type controlling each column family
> - The set of sstables included in each compaction strategy
> - Information about flushes and compactions, including times and all involved sstables
> - Information about sstables, including generation, size, and tokens
> - Any additional metadata the strategy wishes to add to a compaction or an sstable, like the level of an sstable or the type of compaction being performed
