--policy-relay-from-slave
Cross-site replicators within a Composite Active/Active deployment can be configured to point to Replicas by default, and to prefer Replicas over Primaries during operation. In a standard deployment, cross-site replicators work via Primaries at each cluster site to read the remote information. To configure the service to use Replicas in preference to Primaries, use the --policy-relay-from-slave=true option to tpm. Both Primaries and Replicas remain in the list of possible hosts, so if no Replicas are available during a switch or failover event, then a Primary will be used.
--prefer-ip-stack
--preferred-path
Specifies one or more additional directories that will be added
before the current PATH environment variable when
external commands are run from within the backup environment.
This affects all external tools used by Tungsten Cluster,
including MySQL, Ruby, Java, and backup/restore tools such as
Percona Xtrabackup.
One or more paths can be specified by separating each directory
with a colon. For example:
shell> tpm ... --preferred-path=/usr/local/bin:/opt/bin:/opt/percona/bin
The --preferred-path
information propagated to all remote servers within the
tpm configuration. However, if the staging
server is one of the servers to which you are deploying, the
PATH must be manually updated.

When enabled (default), the configuration that contain user,
password and other information are configured so that they are
only readable by the configured user. For example:
