high commonswiki_p replag on labs:
MariaDB [commonswiki_p]> SELECT lag FROM heartbeat_p.heartbeat JOIN meta_p.wiki ON CONCAT(shard, '.labsdb') = slice WHERE dbname = 'commonswiki'; +--------+ | lag | +--------+ | 105833 | +--------+ 1 row in set (0.01 sec)
MariaDB [commonswiki_p]> SELECT lag FROM heartbeat_p.heartbeat JOIN meta_p.wiki ON CONCAT(shard, '.labsdb') = slice WHERE dbname = 'commonswiki'; +------+ | lag | +------+ | 0 | +------+ 1 row in set (0.01 sec)
I do not think this task is still necessary, the problem is solved.
