What are common pitfalls with GTID replication?

GTID (Global Transaction Identifier) replication in MySQL can be a powerful feature for maintaining synchronized databases, but it comes with its own set of challenges. Below are some common pitfalls that database administrators should be aware of:

• Misconfiguration: Failing to properly configure GTID settings can lead to replication issues. Ensure that gtid-mode is enabled and set correctly on both master and slave servers.
• Transaction Conflicts: GTIDs can lead to conflicts if the same transaction is executed on different servers simultaneously, which can result in replication errors.
• Backup and Restore Complications: Restoring a backup from a GTID-enabled server without careful attention to GTID values may lead to issues where the slave cannot synchronize with the master.
• Network Latency: High latency or unreliable network connections can affect the performance of GTID replication, leading to desynchronization between master and slave.
• Recovery and Failover Issues: Setting up recovery and failover processes for GTID replication can be complex, and without proper planning, it can lead to data inconsistency.

To mitigate these challenges, ensure thorough testing and proper documentation of your replication configurations.
