v1.1 (Current) ✅ ​

Focus

Cross-namespace support and operational improvements

New Features ​

  • ✅ Helm Chart Distribution

  • ✅ Cross-Namespace Resource Provisioning

    • Support creating node resources in different namespaces using targetNamespace field
    • Uses label-based tracking (lynq.sh/node, lynq.sh/node-namespace) for cross-namespace resources
    • Automatic detection: same-namespace uses ownerReferences, cross-namespace uses labels
    • Dual watch system: Owns() for same-namespace + Watches() with label selectors for cross-namespace
    • Enables multi-namespace node isolation and organizational boundaries

  • ✅ Orphan Resource Cleanup

    • Automatic detection and cleanup of resources removed from templates
    • Status-based tracking with appliedResources field
    • Respects DeletionPolicy (Delete/Retain)
    • Orphan labels for retained resources for easy identification

v1.2 ​

Focus

Additional datasources and enhanced observability

New Features ​

  • [ ] PostgreSQL Datasource

    • Full PostgreSQL support
    • Connection pooling
    • SSL/TLS support
    • Query optimization

  • [ ] Enhanced Metrics Dashboard

    • Pre-built Grafana dashboards
    • Comprehensive AlertManager rules

v1.3 ​

Focus

Scalability and advanced multi-tenancy features

New Features ​

  • [ ] Node Sharding for Large-Scale Deployments

    • Horizontal sharding of node workloads across multiple operator instances
    • Shard key-based node distribution
    • Load balancing across shards
    • Shard rebalancing and migration support
    • Use cases:
      • Supporting 10,000+ nodes per cluster
      • Isolating node failures to specific shards
      • Reducing controller resource consumption
      • Enabling independent scaling of operator replicas

  • [ ] Advanced Multi-Tenancy Isolation

    • Node priority and resource quotas
    • Per-node rate limiting
    • Node lifecycle hooks
    • Custom node tagging and filtering

Improvements ​

  • [ ] Enhanced reconciliation performance for large node counts
  • [ ] Improved status reporting and aggregation
  • [ ] Optimized database query batching
  • [ ] Better scaling metrics and recommendations
