Subject [jira] Commented: (CASSANDRA-825) Create an additional system keyspace to store KS definitions and migration data.
Date Thu, 04 Mar 2010 18:01:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12841413#action_12841413
] 

Jonathan Ellis commented on CASSANDRA-825:
------------------------------------------

fixMaxId is never called?

wrapping an AtomicInteger w/ synchronized isn't the end of the world but it's kind of ugly.

Maybe using a wrapper class like in CommitLog to avoid explicit synchronization but still
getting laziness would work here instead?
