MySQL Replication Delay Analysis and Troubleshooting for Large Transactions

The article describes a MySQL 5.7.31 replication delay where Seconds_Behind_Master fluctuates between 0 and over 10,000 seconds, analyzes root causes such as single‑threaded replication, large or long‑running transactions, and provides preventive, diagnostic, and remediation steps including enabling parallel replication and using the infobin tool.

Why MySQL Replication Lags During Long ALTERs and MyISAM Locks—and How to Fix It

The article examines two common MySQL master‑slave delay scenarios—slow ALTER operations and MyISAM table‑level locks—explains why they cause replication lag, and offers practical mitigation steps such as scheduling problematic SQL, isolating lagging slaves, and tuning binlog write settings.
