MySQL Error 4019: GTID Clauses with Anonymous Transactions
Description
This error occurs when attempting to use `SQL_AFTER_GTIDS` or `SQL_BEFORE_GTIDS` with `START REPLICA` on a MySQL replication channel. It specifically happens when that channel is configured to assign GTIDs to anonymous transactions (using `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS`). This configuration creates a conflict, as the server is already managing GTID assignment for such transactions.
Error Message
The SQL_AFTER_GTIDS or SQL_BEFORE_GTIDS clauses for START REPLICA cannot be used when the replication channel is configured with ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS = LOCAL|<UUID>.
Known Causes
3 known causesConflicting Replication Settings
The replication channel is configured to automatically assign GTIDs to anonymous transactions, which conflicts with explicitly specifying GTID starting points for replication.
Improper START REPLICA Syntax
The `START REPLICA` command includes `SQL_AFTER_GTIDS` or `SQL_BEFORE_GTIDS` clauses on a channel where `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS` is enabled.
Inconsistent GTID Strategy
An attempt to mix different GTID management strategies on the same replication channel, leading to logical inconsistencies.
