> Current 0.12.0 release has some major issues:
> 1. Coordinator loses leadership
> 2. Newly introduced Quantiles sketch is broken
> 3. Coordinator+overlord web console broken
> 1. is especially very important. Without a coordinator, druid stops
> With bug 5561, it is impossible to use druid for long periods since
> coordinator eventually does lose leadership and the whole process needs to
> be restarted for it to come back.
> *Why not wait till 0.13.0?*
> A lot of companies like to update one version at a time and may not want
> to jump directly to 0.13.0.
> Those companies will hit a bad surprise due to bug 5561 essentially
> rendering the cluster useless in production.
> Also quantiles being the new feature and broken does not look good either.
> 0.12.0 is a 'release', not an RC, thus marking it good for production, but
> the bugs listed above prevent it from being used as such.
> I highly recommend 0.12.1 release, thus marking the right version to
