Tellier Benoit updated MAILBOX-296:
-----------------------------------
Component/s: cassandra
> Improve Expunges over Cassandra
> -------------------------------
>
> Key: MAILBOX-296
> URL: https://issues.apache.org/jira/browse/MAILBOX-296
> Project: James Mailbox
> Issue Type: Improvement
> Components: cassandra
> 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.
