> Instead of writing the the stats table directly in the thread performing major compaction, we should instead write to it asynchronously, perhaps using the same asynchronous mechanism used by tracing. Apparently HBase used to have a "custodian" table where they'd write as compaction and other background tasks were running, and this leads to bad things happening if the table being written to can't be reached.
