Replication Manager is a high-availability orchestrator for MariaDB, MySQL, and Percona Server replication topologies.

The main features are:

Replication & Topology

  • Replication monitoring with support for GTID, multi-source, and delayed replication
  • Topology detection and leader election across async, semi-sync, multi-master, mesh, wsrep, group replication, and relay topologies
  • Controlled replica-to-primary promotion (switchover)
  • Automatic primary election on failure detection (failover)
  • Replication best-practice enforcement
  • Near-zero data loss targeting across most failure scenarios
  • Automatic database rejoining and reseeding

Cluster Management

  • Multi-cluster management from a single instance
  • SLA tracking
  • Traffic capture on high load
  • Staging with multi-source clusters
  • Scriptable states and events
  • Remote script execution via SSH

Proxy Integration

Backup & Recovery

  • Logical and physical backups via mysqldump, mydumper, mariabackup, and xtrabackup
  • Snapshot backups and point-in-time recovery via Restic
  • S3-compatible object storage backend for backup repositories
  • Automated log archiving and table defragmentation

Observability & Alerting

  • Metrics history exposed via the Carbon/Graphite API
  • Alerting via email, Pushover, Slack, Teams, and Mattermost
  • Per-module log level configuration

Operations & Security

  • Built-in database and proxy configurator
