------------------------------------
Summary: Improve performance of selectors with a big sequence of
OR and AND logical expressions
Key: AMQ-8613
URL: https://issues.apache.org/jira/browse/AMQ-8613
Project: ActiveMQ
Issue Type: Improvement
Components: JMS client
Affects Versions: 5.17.1
Reporter: Enrico Olivelli
Currently when you create a selector with OR and ANDs the filter creates a huge
stack trace.
This is because for each element in the OR and AND expression node we have to
execute a method call.
This is happening because OR and AND expressions are treated as
BinaryExpressions.
A very simple but effecting improvement is to not represent OR and AND
expressions as binary expression but store the list of siblings expression in
only one node.
