Re: Rate Quota
Hi Huizhi, I am also looking for this rate quota per client feature. Would you mind sending again the picture from the Facebook presentation, as I didn't see that attachment.

[jira] [Created] (ZOOKEEPER-4187) Support compressed data natively
David Smiley created ZOOKEEPER-4187: --- Summary: Support compressed data natively Key: ZOOKEEPER-4187 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4187 Project: ZooKeeper Issue Type: Improvement Reporter: David Smiley I think it's common to put files in ZooKeeper that compress well, sometimes extremely well. The client (perhaps facilitated by Curator) can compress this, but it'd be nicer I think if ZK supported this natively. Wether a file is compressed or not could be the choice of the client, and the ZK client could just do it for the user (ease of use), provided you have the appropriate dependency. The server need not do any compression; leave it to the client. A ZK client could tell the server what compression algorithms it supports, so that if a client (perhaps an old one) doesn't have the compression libs needed for a given file it wants, the server could decompress on its behalf. That should handle backwards-compatibility. -- This message was sent by Atlassian Jira (v8.3.4#803005)
Re: [VOTE] Apache ZooKeeper release 3.7.0 candidate 0
+1 - xsum/sig validated. Compiles/runs fine on macos+jdk11. Verified some larger ensemble sizes manually and it worked ok. I looked at a few of the new features listed - they look great! I did notice some changes without documentation though (whoami eg), would be good for committers to ensure that docs get updated along the way... Thanks Damien for acting as RM.
