Subject [jira] Commented: (ZOOKEEPER-104) KeptSet: a distributed data stucture backed by the children of a ZooKeeper node
Date Fri, 01 Aug 2008 16:28:31 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619061#action_12619061
] 

Benjamin Reed commented on ZOOKEEPER-104:
-----------------------------------------

I think we should convert to a runtime exception. (It really seems like InterruptedException
should be runtime in the first place...) It looks like this is how other APIs that implement
persistent sets work.

There is another possiblity: keep the whole set in memory and use watches as cache invalidations.
Then you could have commit() and refresh() operations that would throw the exceptions. Depending
on the size of the sets it does seem wise to keep it all cached in the client so that read
operations can be executed quickly. Even the commit() allows you to batch up changes and do
them faster as well.
