Orchestrator
Orchestrator es un sistema de alta disponibilidad y gestor de replicación para clusters de bases de datos MySQL. Funciona como un automatizador de failover y visualizador de topología diseñado para detectar fallos del maestro y promover réplicas en espera para minimizar el tiempo de inactividad del sistema.
El proyecto se centra en la gestión y reconfiguración de topologías de replicación de MySQL para mantener una distribución de datos consistente. Utiliza el rastreo de descubrimiento de topología para mapear estructuras de replicación e identifica fallos activos dentro del cluster de bases de datos.
El sistema proporciona capacidades para la recuperación automatizada de clusters, seguimiento de instancias con conocimiento de ubicación y reconfiguración de topología basada en restricciones. También mantiene un registro de auditoría de grabación de estado para rastrear cambios históricos de topología y eventos de failover.
Features
- MySQL Replication Failover Tools - Detects master failures and triggers automated promotions based on the state of the MySQL replication graph.
- Database Replication Topology Discovery - Actively probes database metadata to detect the real-time structure of replication chains and identify broken links.
- MySQL Topology Visualizers - Provides a real-time visualization of MySQL replication structures to identify failures and map the cluster topology.
- MySQL Replication Topology Managements - Organizes the replication graph of database clusters to ensure consistent data distribution and availability.
- MySQL Replication Topology Visualizations - Maps and audits the structure of MySQL replication graphs to identify failures and track instance locations.
- MySQL High Availability Automations - Automates the failover and recovery of MySQL database clusters to ensure continuous system uptime.
- Automated Master Failovers - Promotes a standby replica automatically when a master failure occurs to maintain continuous availability.
- Database Topology Graphs - Builds and displays a directed graph representing the current replication hierarchy and data flow.
- Database Replication Failure Recoveries - Executes recovery processes to restore a healthy database state after detecting master or intermediate failures.
- Replication Topology Refactorings - Moves replicas between masters using validation rules to ensure the new configuration is safe.
- Database Topology Location Tracking - Records the physical location or datacenter of database instances to inform decisions during recovery and replication.
- Datacenter-Aware Instance Tracking - Associates database nodes with physical datacenters to optimize failover decisions based on geographic proximity.
- Replication Routing Constraints - Validates the legality of moving replicas between masters using predefined safety and routing rules.
- Database Tools - MySQL replication topology manager and visualizer.
- Database Utilities - MySQL replication topology manager with visualization.
- Chaos Engineering Tools - Manages MySQL replication topology and high availability.
