This option enables batch mode for a service, which ensures that replication services that are writing to a target database using batch mode in heterogeneous deployments (for example Hadoop, Amazon Redshift or Vertica). Setting this option enables the following settings on each host:
On a Primary
mysql-use-bytes-for-string

colnames filter is
enabled (in the
binlog-to-q stage
to add column names to the THL information.
pkey filter is
enabled (in the

the right primary key information.

The default behavior of this property is different in certain installs.
For a cluster node install that INCLUDES the manager process, AND where the
install OS user is NOT root, the default will be true
For a Replicator only or Connector only install, the default will be false
When set to true, the property has the following effect:
During staging tpm installs, if the tungsten user is different from the ssh user on remote hosts
All startup scripts when using systemctl: replicator, connector, manager will call systemctl prefixed with sudo:
for example: sudo -n systemctl start treplicator
tprovision script (tps.pl) requires sudo access for mysql and xtrabackup calls
replicator backup script for xtrabackup and other backup utilities
check_tungsten.sh utility to call xinetd
tmonitor starts exporter service with sudo
manager to restart mysql service when found stopped
tpm diagnostic operation (tpm diag)

| Option | --executable-prefix | |
| Config File Options | executable-prefix | |
| Description | Adds a prefix to command aliases | |
| Value Type | string | |
When enabled, the supplied prefix is added to each command alias
that is generated for a given installation. This enables
multiple installations to co-exist and and be accessible through
a unique alias. For example, if the executable prefix is
configured as east, then
an alias for the installation to trepctl will
be created as east_trepctl.
Alias information for executable prefix data is stored within
the
$CONTINUENT_ROOT/share/aliases.sh
file for each installation.
