Managed Service for Apache Kafka requires each cluster to have equal resources in each
of the three zones. Single-zone or two-zone Managed Service for Apache Kafka clusters
are not supported.
You cannot choose the zones when you create the cluster.
You cannot configure the volume of local storage on a cluster.
Managed Service for Apache Kafka runs in theKRaft mode.
Zookeeper mode is not supported.
JMX APIs for metrics are not supported.
Topic compression withzstdis not supported. Supported values
forcompression.typeincludelz4,gzip,snappy, anduncompressed.
While you can change broker
configurations withread-onlyupdate mode at any time, these changes
take effect only when the brokers restart. Restarts happen periodically as part
of Google's maintenance and upgrade processes, but there's no set schedule or a
way to manually trigger them. As a result, you can't control when
these changes take effect. Examples ofread-onlyconfigurations includeauto.create.topics.enableandbackground.threads.
Updates to configurations with thecluster-wideupdate mode, such asmessage.max.bytes, don't require restarts and take effect immediately.
Some broker configuration parameters are managed by the service
and cannot be updated. This includesbroker.idand storage-related settings, such asremote.log.storage.system.enable.
