orchestrator is a MySQL high availability and replication management tool, runs as a service and provides command line access, HTTP API and Web interface.
It requires its own MySQL database as a backend server to store all information related to the Orchestrator managed database cluster topologies.
Orchestrator only needs a MySQL user with limited privileges (SUPER, PROCESS, REPLICATION SLAVE, RELOAD) to connect to the database servers.
The original openark/orchestrator repository was archived in February 2025 and is no longer maintained there. Percona provides a fork containing changes developed primarily for its Kubernetes Operators. Percona does not present itself as the general public maintainer of the original project, so administrators should assess the available fork and maintenance arrangements before adopting the software for new deployments.
Key Features
- Discovery – actively crawls through your topologies and maps them. It reads basic MySQL info such as replication status and configuration.
- Refactoring – understands replication rules. It knows about binlog file:position, GTID, Pseudo GTID, Binlog Servers.
- Recovery – uses a holistic approach to detect master and intermediate master failures. Based on information gained from the topology itself, it recognizes a variety of failure scenarios.
- Interface that supports:
- Command line interface.
- Web API (HTTP GET access).
- Web interface.
- Topology and status of the replication tree is automatically detected and monitored
- Highly available.
- Supports many different types of topologies, from a single master -> slave to complex multi-layered replication trees consisting of hundreds of servers
- Controlled master takeovers.
- Supports automatic failover of the master, and the replication tree can be fixed when servers in the tree fail – either manually or automatically.
- Manual failovers.
- Failover auditing.
- Audited operations.
- Pseudo-GTID.
- Datacenter/physical location awareness.
- MySQL-Pool association.
- HTTP security/authentication methods.
- An orchestrator-mysql Google groups forum to discuss topics related to orchestrator.
