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.
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.
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.
