MySQL Error 1841: GTID_PURGED Active Transactions
Description
This error indicates an attempt to modify the `@@GLOBAL.GTID_PURGED` system variable while the MySQL server detects one or more active transactions. `GTID_PURGED` tracks the set of GTIDs that have been purged from the binary log, crucial for Global Transaction ID (GTID) based replication and point-in-time recovery. The server prevents this change to maintain data consistency and prevent replication issues.
Error Message
@@GLOBAL.GTID_PURGED can only be set when there are no ongoing transactions (not even in other clients).
Known Causes
4 known causesActive Transactions in Current Session
The client attempting to set `GTID_PURGED` has an open transaction (e.g., `START TRANSACTION` without `COMMIT` or `ROLLBACK`).
Active Transactions in Other Sessions
Other connected client applications or users have ongoing transactions on the MySQL server.
Long-Running Server Operations
Background processes or administrative tasks that are treated as transactions by the server are still active.
Replication Lag or Open XA Transactions
A replica server might have open transactions due to lag, or there might be distributed (XA) transactions not yet committed or rolled back.
