Get familiar with Streams Replication Manager and its components.
Streams Replication Manager (SRM) is an enterprise-grade replication solution that enables fault tolerant, scalable and robust cross-cluster Kafka topic replication. SRM provides the ability to dynamically change configurations and keeps the topic properties in sync across clusters at high performance. SRM also delivers custom extensions that facilitate installation, management and monitoring making SRM a complete replication solution that is built for mission critical workloads. Streams Replication Manager consists of two main components. The Stream Replication Engine and the Stream Replication Management Services.
- Stream Replication Engine
The Stream Replication Engine is a next generation multi-cluster and cross-datacenter replication engine for Kafka clusters.
- Stream Replication Management Services
Stream Replication Management Services are services powered by open source Cloudera extensions which utilize the capabilities of the Stream Replication Engine. These services provide:
- Easy installation
- Lifecycle management
- Management and monitoring of replication flows across clusters
The Stream Replication Management Services includes the following custom extensions:
- Cloudera SRM Driver
The Cloudera SRM Driver is a small wrapper around the Stream Replication Engine that adds the extensions provided by Cloudera. It provides the ability to spin up SRM clusters and has a metrics reporter. The driver is managed by Cloudera Manager and is represented by the Streams Replication Manager Driver role.
- Cloudera SRM Client
The Cloudera SRM Client provides users with command line tools that enable replication management for topics and consumer groups. The command line tool associated with the Cloudera SRM Client is called
- Cloudera SRM Service
The Cloudera SRM Service consist of a REST API and a Kafka Streams application to aggregate and expose cluster, topic and consumer group metrics. The service is managed by Cloudera Manager and is represented by the Streams Replication Manager Service role.
