MySQL Slave Replication Lag

Back to Runbooks


MySQL Slave Replication Lag is an incident that occurs when there is a delay or lag in the replication of data from the master MySQL server to the slave MySQL server. This can happen due to various reasons such as network latency, high load on the master server, or configuration issues. This can lead to data inconsistency and affect the overall performance of the application or service that relies on the MySQL database.
