Alexander Shraer commented on ZOOKEEPER-2016: --------------------------------------------- IIRC watch notifications are done by the follower to which a client is connected, not by leader. Even if we're talking about a few hundreds clients per server I'm not sure its a problem for the server. > Automate client-side rebalancing > -------------------------------- > > Key: ZOOKEEPER-2016 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2016 > Project: ZooKeeper > Issue Type: Improvement > Reporter: Hongchao Deng > > ZOOKEEPER-1355 introduced client-side rebalancing, which is implemented in > both the C and Java client libraries. However, it requires the client to > detect a configuration change and call updateServerList with the new > connection string (see reconfig manual). It may be better if the client just > indicates that he is interested in this feature when creating a ZK handle and > we'll detect configuration changes and invoke updateServerList for him > underneath the hood. -- This message was sent by Atlassian JIRA (v6.2#6252)
