What's New in Streams Replication Manager

SRM Service Multi Target Cluster Support

The SRM Service can now target and monitor multiple Kafka clusters. Previously, the Service could only target a single cluster. Targeting multiple clusters enables you to monitor multiple remote Kafka clusters using a single SRM deployment. Configuration is done in Cloudera Manager by adding multiple target Kafka cluster aliases to the Streams Replication Manager Service Target Cluster property. For more information, see Configuring the service role target cluster.

SRM Service Remote Querying [Technical Preview]

A new feature, Remote Querying, is introduced for the SRM Service. Remote Querying enables the SRM Service to query other, remote SRM Services and fetch the metrics gathered by the remote SRM Services. This allows users to monitor all replications of a deployment that has multiple instances of SRM with a single SRM Service. For more information, see Remote Querying and Configuring Remote Querying.

Auto topic creation is disabled by default on source clusters

A new Connector property, disable.source.topic.auto.creation, is introduced. This property controls whether auto topic creation is enabled for SRM’s internal consumers that fetch data from source clusters. This property is enabled by default meaning that auto topic creation is disabled by default. This property is not directly available for configuration in Cloudera Manager, and does not have a dedicated configuration entry on the UI. Instead, it can be configured through the Streams Replication Manager's Replication Configs Cloudera Manager property. Configuration is possible on a global or replication level.
