srm-driver

Learn how to use the srm-driver command line tool which is used to launch SRM.

SRM is launched with the srm-driver command line tool. The driver is responsible for connecting to the specified clusters and performing replication between them. The driver uses a configuration file to identify which clusters it should connect to. When not specified otherwise, it uses the default configuration file. If required, you can use the --config option to specify a different configuration file.

Run the driver with the following command:
srm-driver

By default the driver will read from and write to all clusters specified in the configuration file. Optionally you can use the --clusters option which is used to specify the clusters that the driver should target or in other words write to.

When the driver is started with the --clusters option it will still connect to and read data from all clusters specified in the configuration file, but will only write data to the clusters specified with the --clusters option. This allows you to distribute replication workloads.

Target specific clusters with the following command:
srm-driver --clusters [CLUSTER_1] [CLUSTER_2]

Although the driver launches SRM, it does not kick off replication. Data will only be replicated between clusters once the whitelist is populated with either topics or groups using the srm-control tool.
