* DBA: Figure it out. Compression related? But InnoDB compressed tables should have been replaced with TokuDB...
* Analytics: Check out eventlogging consumer with analytics. The haproxy on dbproxy1004 redirected traffic to db1047, bu did the consumer like that? Do we (a DBA) need to sync events back to the master, or just do a backfill?
