Description: GTID-unsafe transactions refer to those operations in a database that cannot be reliably replicated in a GTID-based replication environment. The GTID (Global Transaction Identifier) is a mechanism that uniquely identifies each transaction in a replication system, facilitating synchronization between master and slave servers. However, certain transactions, such as those involving non-deterministic operations or those dependent on session variables, may result in inconsistencies if replicated. This is because the state of the transaction may vary between the master and slave servers, leading to errors or data loss. Transactions considered ‘gtid_unsafe’ are those that do not meet the necessary requirements for safe replication. Identifying these transactions is crucial for maintaining data integrity in a replication environment, as it allows database administrators to make informed decisions about how to handle replication and avoid potential issues. In summary, ‘gtid_unsafe_trans’ is a fundamental concept in database replication that helps ensure the consistency and reliability of transactions in distributed systems.
