orchestrator – MySQL high availability and replication management tool

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.

Features include:

  • 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.
