Slack digest for #general - 2018-02-01

2018-02-01 04:46:45 UTC - Jaebin Yoon: is the master good to use for testing? Would it be compatible with old bookies (4.3.1.83-yahoo)?
----
2018-02-01 04:55:15 UTC - Matteo Merli: @Jaebin Yoon it is compatible, as always across versions. The only thing is that we found a performance regression in current master (related to the upgrade from netty 4.1.12 to 4.1.20). We have the fix for that and I have it running since few hours and looking good. 
----
2018-02-01 05:10:28 UTC - Jaebin Yoon: I see. then I'll wait until that fix in to master. let me know when it's in. I can use 1.21 for now.
----
2018-02-01 09:52:25 UTC - Ivan Kelly: @Matteo Merli is there also a performance issue besides the object cleaner issue?
----
2018-02-01 23:08:39 UTC - Matteo Merli: @Ivan Kelly Yes, after upgrading Netty, that triggered allocating unpooled direct bytebuffers and that’s super-heavy on GC: <https://github.com/apache/bookkeeper/pull/1108>

2018-02-01 23:15:09 UTC - Ivan Kelly: ah
