MHA Manager is the manager component of the Master High Availability Manager and tools for MySQL (MHA), written in Perl. It automates MySQL master failover and fast master switch by coordinating with MHA node agents on database servers.
Use cases
- automate MySQL master failover when the primary database crashes
- perform fast planned master switchover with minimal downtime
- monitor MySQL replication topology health
- promote the most up-to-date replica to master during failover
- minimize replication lag and data loss during failover
When to choose
- you run MySQL replication and need automated, fast master failover
- you want to minimize downtime and data loss during master crashes
- you need planned master switches for maintenance with near-zero downtime
When to avoid
- you use MariaDB, MySQL Group Replication, or Galera Cluster with built-in failover
- you want an actively developed tool with modern MySQL 8 feature support
- you need a cloud-managed HA solution rather than self-managed replication
