Description: The term ‘gtid_unsafe_trans_set’ refers to a set of transactions in a database system that are not safe for replication using Global Transaction Identifiers (GTID). In the context of database replication, GTIDs are unique identifiers that allow tracking and managing transactions in a replicated environment. When discussing ‘unsafe’ transactions, it refers to those that may not be reliably replicated between the master server and replica servers. This can occur for various reasons, such as the lack of support for certain operations in GTID replication mode or the presence of transactions that do not meet the necessary requirements for safe replication. Identifying these transactions is crucial for maintaining data integrity and consistency in a replication environment, as any inconsistency could lead to errors in data synchronization between nodes. Therefore, the ‘gtid_unsafe_trans_set’ acts as an alert mechanism for database administrators, indicating that they should review and possibly adjust their transactions to ensure that all are safe for GTID replication.
