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.
- 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.
- Datacenter/physical location awareness.
- MySQL-Pool association.
- HTTP security/authentication methods.
- An orchestrator-mysql Google groups forum to discuss topics related to orchestrator.
