QPID-8488: [Broker-J] Enhance ACL rule with multi-value properties
This closes #116
> [Broker-J] Enhance ACL rule with multi-value properties
> -------------------------------------------------------
>
> Key: QPID-8488
> URL: https://issues.apache.org/jira/browse/QPID-8488
> Project: Qpid
> Issue Type: Improvement
> Components: Broker-J
> Reporter: Marek Laca
> Priority: Minor
> Labels: ACL, Broker, Java
>
> We are using an extensive set of the ACL rules. Our set contains a lot of
> rules that differ only in single value. For example:
> {code:none}
> ACL ALLOW CON_USER CONSUME QUEUE name="broadcast.ABC.Public"
> ACL ALLOW CON_USER CONSUME QUEUE name="broadcast.ABC.Private"
> ACL ALLOW CON_USER CONSUME QUEUE name="broadcast.ABC.Repeat"
> ACL ALLOW CON_USER CONSUME QUEUE name="response.ABC"
> ACL ALLOW CON_USER CONSUME QUEUE name="error.ABC"
> {code}
> These rules differ only in "name" property, hence if the "name" was a
> multi-value property then it would allow us to merge the rules into one:
> {code:none}
> ACL ALLOW CON_USER CONSUME QUEUE name=[broadcast.ABC.Public,
> broadcast.ABC.Private, broadcast.ABC.Repeat, response.ABC, error.ABC]
> {code}
> The multi-value functionality would decrement the amount of our rules
> substantially and improves the broker throughput.
> *Proposed solution:*
> We could set up multiple possible values as a comma separated list in
> brackets. The multi-values property can be implemented as the compressed
> prefix tree that checks an input string in linear time.
> This task depends on the
> [QPID-8487|https://issues.apache.org/jira/browse/QPID-8487] because the
> refactoring of [QPID-8487|https://issues.apache.org/jira/browse/QPID-8487]
> clears the way for an effective implementation.
