MySQL Error 4039: Replication UUID Conflicts with View Change
Description
This error occurs when attempting to configure a MySQL replication source using the `CHANGE REPLICATION SOURCE TO ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS` command. It indicates that the provided UUID for anonymous transactions is identical to the `group_replication_view_change_uuid`, which is an internal identifier used by MySQL Group Replication. This conflict prevents the replication source change from being applied.
Error Message
CHANGE REPLICATION SOURCE TO ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS = <UUID> cannot be executed because the UUID value is equal to the group_replication_view_change_uuid.
Known Causes
3 known causesUUID matches Group Replication internal ID
The UUID provided for `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS` is identical to the `group_replication_view_change_uuid`, which is reserved for internal Group Replication state tracking and must not be reused.
Incorrect UUID generation or selection
An accidentally chosen or manually entered UUID for the replication source happens to match an internally managed Group Replication UUID, leading to a collision.
Conflict with active Group Replication state
This error typically arises in environments where Group Replication is active or has recently been active, and an attempt is made to reuse one of its critical internal UUIDs for a different purpose.
