The EXTRA_KAFKA_CONFIGS_FILE configuration variable has been deprecated and planned to be removed no earlier than version 1.225.0. For more information, see RN Issue.

rdns() has been deprecated and will be removed in version 1.249. Use reverseDns() as an alternative function.

For clusters using secondary storage where the primary storage on some nodes in the cluster may be getting filled (i.e. the storage usage on the primary disk is halfway between PRIMARY_STORAGE_PERCENTAGE and PRIMARY_STORAGE_MAX_FILL_PERCENTAGE), those nodes may fail to transfer segments from other nodes. The failure will be indicated by the error java.nio.file.AtomicMoveNotSupportedException with message "Invalid cross-device link".

This does not corrupt data or cause data loss, but will prevent the cluster from being fully healthy, and could also prevent data from reaching adequate replication.
