-------------------------------------
Summary: Remove useless index on Cassandra subscriptions
Key: JAMES-1876
URL: https://issues.apache.org/jira/browse/JAMES-1876
Project: James Server
Issue Type: Bug
Reporter: Tellier Benoit
Subscriptions are accessed by user and optionally by Mailbox
Mailbox name is used as partition key.
Hence, an Index is needed for retrieving a user subscription.
- This is ineficient : we could directly use user as primary key, and mailbox
as a clustering key, thus not requiring additional indexes.
- This brakes scalability : several users can register relative path, and
let's say there INBOX. Hence, data and load distribution is then broken.
