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.
