Summary: [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
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.
