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:
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:
The multi-value functionality would decrement the amount of our rules substantially and improves the broker throughput.
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 because the refactoring of QPID-8487 clears the way for an effective implementation.
