Support for source_retry_count and master_retry_count in replication ?

[dibrother]

Question:
Due to the default value of 10 for MySQL 8.4 Source-Retry-Count, if the main server fails to connect within 10 attempts after a crash, it will cause the io_thread to permanently fail to connect. Therefore, I have changed the value of Source-Retry-Count to 10080.
After switching or error recovery, when configuring the master-slave relationship in the replication manager, Source_SetryCount is not set, and the value of the slave library is set to 10 by default.
Is there a parameter that can modify this setting value?

Hi, seems we will add this feature.

We will have this in Mariadb 12:
https://mariadb.com/docs/server/reference/sql-statements/administrative-sql-statements/replication-statements/change-master-to#master_retry_count

• those parameters should be discovered from the master and propagate in change master
• the parameter should be changeable via api and imposed by sysops dbops
