struct ovsdb;

/* Replication module runs when OVSDB server runs in the backup mode.
 *
 * API Usage
 *===========
 *
 * - replication_init() needs to be called whenever OVSDB server switches into
 *   the backup mode.
 *
 * - replication_add_local_db() should be called immediately after to add all
 *   known database that OVSDB server owns, one at a time.
 *
 * - replication_destroy() should be called when OVSDB server shutdown to
 *   reclaim resources.
 *
 * - replication_run(), replication_wait(), replication_is_alive() and
 *   replication_get_last_error() should be call within the main loop
 *   whenever OVSDB server runs in the backup mode.
 *
 *  - set_blacklist_tables(), get_blacklist_tables(),
 *    disconnect_active_server() and replication_usage() are support functions
 *    used mainly by uinxctl commands.
