Apache Pinot

qq, do you recommend setting `controller.enable.batch.message.mode` to true? I see a github <https://github.com/apache/pinot/pull/3928|issue> from pinot 0.2.0 that switched it to false by default due to high controller gc. Do you think it's safe to enable now? Pinot has evolved a lot since then. :slightly_smiling_face:

context: we have a lot of tables with tiny segments, and we are going through and fixing them, but in the meantime we notice a huge amount of zk messages, mostly from broker resource and the tables w tiny segments.

If anything we can try and let you know how it goes, unless you recommend not to even try it.

Sorry to bug you guys: <@UDQU92KBK> <@UDT7GFEG6> <@UGRJA9TEH> do you think it's safe to enable batch mode on the controllers?

This flag is actually passed to Helix, and I don't think we have upgraded Helix since `0.2.0`. I'm not sure if the issue described in the PR applies to you, so I would suggest enabling it in a staging cluster and monitor how it works

nice, thanks! Will let you know how it goes.
