MySQL Error 3077: Invalid Replication Repository Type
Description
This error occurs when MySQL replication is configured for multiple channels, but the replication repository is set to `FILE` instead of `TABLE`. MySQL requires a `TABLE` type repository to correctly manage and store metadata for multiple replication channels. You will encounter this error when starting or reconfiguring a replica with an incompatible repository setting.
Error Message
To have multiple channels, repository cannot be of type FILE; Please check the repository configuration and convert them to TABLE.
Known Causes
3 known causesIncorrect Repository Type Configuration
The MySQL replica's configuration explicitly specifies the replication repository type as `FILE` while attempting to use multiple replication channels.
Default Repository Type Mismatch
The default replication repository type for the MySQL version or specific setup is `FILE`, which conflicts with the requirements for multi-channel replication.
Multi-Channel Migration Oversight
An existing replica, initially configured for single-channel replication with a `FILE` repository, was transitioned to a multi-channel setup without updating the repository type to `TABLE`.
