[jboss-user] [JBoss Messaging] - Re: Behavior with selector and fullSize cache

[timfox]

Yes selectors do not work well with paged messages.

To implement it otherwise would be difficult - we'd have to scan the entire file store for matching messages every time a consumer is added.

If you find yourself needing functionality like this, then it sounds like you need a database not a messaging system!

Databases are designed to do exactly this kind of thing: Large tables of data which can't all fit in memory and "select" subsets of rows matching a criteria.

Messaging systems support this kind of functionality to some extent, but it is not their primary purpose!
