## Feature Request ### Describe the feature you would like. The MySQLNormalReplicationDatabaseDiscoveryProviderAlgorithm uses Seconds_Behind_Master to judge the replication delay, but Seconds_Behind_Master may be inaccurate. I hope to use my own defined SQL to obtain the replication delay. If there is no definition or the table does not exist and other abnormal conditions, I will use Seconds_Behind_Master. # discoveryTypes: # normal-replication: # type: MySQL.NORMAL_REPLICATION # props: # delay-milliseconds-threshold: 10000 # delay-checked-sql: select abs(unix_timestamp(now())-unix_timestamp(max(Ftime))) as delay from dba.delay_monitor limit 1; -- This is an automated message from the Apache Git Service.
