Converting to Fully Synchronous Replication

Convert Semi-Sync to Full Sync

Write a MySQL commands to convert semi-synchronous to fully synchronous replication.

Solution:

-- Disable semi-sync first
SET GLOBAL rpl_semi_sync_master_enabled = 0;

-- Enable synchronous replication
SET GLOBAL rpl_binlog_sender_queues = 1;

-- Ensure all transactions are committed synchronously
SET GLOBAL rpl_binlog_sender_queues_commit_wait_time = 1000000; -- 1 second wait

Explanation:

• Purpose of the Query:
• Shifts from semi-synchronous to fully synchronous replication for higher data consistency at the cost of performance.
• Key Components:
• Disabling semi-sync and enabling synchronous settings.
• Real-World Application:
• Critical for scenarios requiring zero data loss but at the expense of performance.

Notes:

• This configuration can significantly impact write performance.
