             Summary: Improve Expunges over Cassandra
                 Key: MAILBOX-296
                 URL: https://issues.apache.org/jira/browse/MAILBOX-296
             Project: James Mailbox
          Issue Type: Improvement
            Reporter: Tellier Benoit


Large expunges are today failing on Cassandra.

And overall performance does not seem good.

We should pay attention to: 
 - Limiting the number of concurrent queries to avoid killing the server
 - Prepare select statements in MessageDAO
 - Not use IN clause in MessageDAO
 - Use limit on incoming IDs on MessageDAO reads
 - Better chaining of future

We will validate performance gains with gatling-imap tests.
