Regular update release.
Log4j2 updated from 2.9.1 to 2.10.0. If you are using a custom logging configuration, you may need to update your configuration accordingly.
To eliminate GC pauses caused by compression in the Kafka-client in Humio, Humio now disables compression on all topics used by Humio. Humio compresses internally before writing to Kafka on messages where compression is required (Ingest is compressed). This release of Humio enforces this setting onto the topics used by humio. This is the list of topics used by Humio. (Assuming you have not configured a prefix, which is in then used on all of them)
global-events global-snapshots humio-ingest transientChatter-events
You can check the current non-default settings using this command: (Replace the topic name):
cd SOME_KAFKA_INSTALL_DIR ./bin/kafka-configs.sh --zookeeper localhost:2181 --entity-type \ topics --entity-name humio-ingest --describe
Removed GC pauses caused by java.util.zip.* native calls from compressed http-traffic triggering "GCLocker initiated GC", which could block the entire JVM for many seconds.
Reduced query state size for live queries decreasing memory usage.
