While THP can be beneficial for many applications, enabling it on a database server could have unintended consequences. In this post, we will explore THP, its impact on database servers, and how to disable it for optimal performance and stability. As such, it is generally recommended to disable THP for most database workloads.

To start replication on the replica node, simply execute START SLAVE; Of course, this method is not for everyone, as a primary restart is not the recommended approach since it causes downtime for the entire database cluster. Another way to achieve this is by reconfiguring the replica to use the binary log file and position. Sure thing!
