Deprecated master info option used

Production Risk

Low — deprecation warning only; still functional in current version.

What this means

A deprecated replication configuration option related to master info was used; the option will be removed in a future MySQL version.

Why it happens
  1. 1Using options like master-info-file, relay-log-info-file, or other deprecated master_info settings.
  2. 2Configuration file or CHANGE MASTER TO referencing obsolete parameters.
How to reproduce
trigger — this will error
trigger — this will error
CHANGE MASTER TO MASTER_INFO_REPOSITORY = 'FILE'; -- deprecated in MySQL 8.0

expected output

Warning (Code 1800): Using a deprecated 'master_info' option. Please use 'replica_info' options or TABLE repository instead.

Fix

Switch master_info_repository to TABLE

Switch master_info_repository to TABLE
STOP SLAVE;
SET GLOBAL master_info_repository = 'TABLE';
SET GLOBAL relay_log_info_repository = 'TABLE';
START SLAVE;

Why this works

TABLE repository is the recommended modern approach for storing replication metadata.
