Finally! After a couple more release candidates, we are excited to announce the
release of Druid 0.8.3!
Please read the release notes carefully before upgrading. Some config changes
are needed and the update order is slightly different than usual.
This release comes with some fun features such as restorable index tasks, new
sketch aggregators, as well as caching on realtime segments.
Lots of bugs have been squashed, including some really old ones. You should
also see some nice performance improvements on the indexing side, and if you
are running lots of realtime tasks your ZooKeeper cluster should be much much
