MariaDB Error 1763: Authentication Options with SQL Thread
Description
This error indicates an attempt to configure replication authentication options (such as SSL/TLS certificates or keys) while only the SQL thread of the replica is being started or modified. Authentication parameters are relevant for the replica's I/O thread, which establishes the connection to the master, not for the SQL thread which processes events from the relay log. It typically occurs during replication setup or modification.
Error Message
Setting authentication options is not possible when only the Slave SQL Thread is being started.
Known Causes
3 known causesConfiguring Auth During SQL Thread Startup
This occurs when a `CHANGE MASTER TO` command with authentication options is executed, but the subsequent `START SLAVE` command or current slave state implies only the SQL thread is being started or affected.
Misunderstanding Replication Thread Roles
The authentication parameters (e.g., SSL/TLS) are handled by the I/O thread, which connects to the master, not the SQL thread which applies events from the relay log.
Incomplete Slave Restart After Auth Changes
If `CHANGE MASTER TO` includes authentication options, the entire slave (or at least the I/O thread) needs to be stopped and restarted for these changes to take effect properly.
