The default temporary directory for Snappy and Zstd compression is changed
Summary

For Kafka, Streams Messaging Manager and Streams Replication Manager, the default temporary directory for Snappy and Zstd compression is changed.

Previous Behavior

The temporary directory for Snappy (org.xerial.snappy.tempdir) and Zstd (ZstdTempFolder) compression were set to /tmp.

New Behavior

The temporary directories for Snappy and Zstd compression are now set to the following:

  • Kafka - /var/lib/kafka
  • Streams Messaging Manager - /var/lib/streams_messaging_manager
  • Streams Replication Manager - /var/lib/streams_replication_manager

Ensure that each service user has write and execute permission on the directory specific to their service. Otherwise, the service will fail to process compressed messages.

  • The Kafka service user (default: kafka) must have write and execute permission on /var/lib/kafka.
  • The Streams Messaging Manager service user (default: streamsmsgmgr) must have write and execute permission on /var/lib/streams_messaging_manager.
  • The Streams Replication Manager service user (default: streamsrepmgr) must have write and execute permission on /var/lib/streams_replication_manager.
