Managed MongoDB (Percona Server)

Okustera Managed MongoDB delivers enterprise NoSQL document storage powered by Percona Server for MongoDB (PSMDB).

It provides 100% wire protocol compatibility with MongoDB 7.0, enterprise security features, hot physical backups, and automated multi-node replica set election.

Architectural Highlights​

  • Automated Replica Sets: Default 3-node topology with majority voting elections in $< 3$ seconds.
  • Hot Physical Backups: Backups taken with Percona Backup for MongoDB (PBM) directly to Okustera S3 object storage without query locking.
  • In-Memory Rate Limiting & Profiling: Advanced query profiler and resource throttling built directly into the database engine.
  • Ceph NVMe Persistence: WiredTiger storage engine optimized for NVMe write amplification and high-concurrency document operations.
