-----------------------------------
Summary: StellarProcessor should have a static expression cache
Key: METRON-820
URL: https://issues.apache.org/jira/browse/METRON-820
Project: Metron
Issue Type: Bug
Reporter: Casey Stella
We recreate StellarProcessor objects all over the place which do not reuse
their expression caches. This results in a significant performance regression
as we are compiling the expression and then processing for every message,
rather than compiling once and reusing.
