Subject [jira] Commented: (ZOOKEEPER-107) Allow dynamic changes to server cluster membership
Date Fri, 01 Aug 2008 19:52:31 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619109#action_12619109

Benjamin Reed commented on ZOOKEEPER-107:
-----------------------------------------

I think there are two issues here: 1) adding/removing servers to a ZooKeeper cluster and 2)
letting clients know about the change. We should probably separate them. I like the URL idea
for dealing with 1) (especially when used in conjunction with the other idea in this Jira
of defining a URL scheme for ZooKeeper). For 2) I agree with Hiram that it should be stored
persistently at each replica and changed via the replication protocol.

> Currently cluster membership is statically defined, adding/removing hosts to/from the
server cluster dynamically needs to be supported.
