Detailed Description​
From MySQL 8.0.26:Â Waiting for source to send event
The thread has connected to the source and is waiting for binary log events to arrive. This can last for a long time if the source is idle.
If the wait lasts for [replica_net_timeout](https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#sysvar_replica_net_timeout) or [slave_net_timeout](https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#sysvar_slave_net_timeout) seconds, a timeout occurs. At that point, the thread considers the connection to be broken and makes an attempt to reconnect.
