@brief disable the replication applier on server startup --database.replication-applier flag

If false the server will start with the replication applier turned off, even if the replication applier is configured with the autoStart option. Using the command-line option will not change the value of the autoStart option in the applier configuration, but will suppress auto-starting the replication applier just once.

If the option is set to true, ArangoDB will read the applier configuration from the file REPLICATION-APPLIER-CONFIG on startup, and use the value of the autoStart attribute from this file.

The default is true.
