[jira] [Created] (CASSANDRA-21624) Reduce CI console output volume
Brandon Williams created CASSANDRA-21624:
--------------------------------------------
Summary: Reduce CI console output volume
Key: CASSANDRA-21624
URL: https://issues.apache.org/jira/browse/CASSANDRA-21624
Project: Apache Cassandra
Issue Type: Improvement
Reporter: Brandon Williams
Analysis of a (Jenkins console log)[https://ci-cassandra.apache.org/job/Cassandra-5.0/654/] shows ~43MB (41%) is two classes of pure-noise output that stream through the controller and are buffered in the controller heap per the in-flight sh step:
* Python dtest runs stream the cassandra-driver's reconnect loop at DEBUG level. A single flapping dtest-novnode cell produced 14,875 full Python tracebacks (~22MB) plus ~80k cassandra.cluster log lines (~11MB), peak 4.2MB/min.
* Every forked test JVM logs the complete ant command line including the full ~17KB classpath ("Forking using command: [...]") = 1,296 lines = 21.4MB, identical content every time.
