Hello, looks like 3.0.18 can't handle the same write ingest compared to 2.1.18 on the same hardware. Basically it looks like the write path, processing batch messages show 10x higher numbers in regard to on-heap allocations.
I've tried to summarize the finding on the following ticket: https://issues.apache.org/jira/browse/CASSANDRA-15430 Haven't been able to attach the JFR Sessions onto the ticket due to size limits, thus please let me know, if they can be uploaded somewhere else. Would be great, if someone could have a look. Thanks! Thomas The contents of this e-mail are intended for the named addressee only. It contains information that may be confidential.
