Niladri Halder developed robust upgrade and lifecycle management features for the openebs/mayastor-control-plane repository, focusing on safe resource deletion and cluster resilience. He implemented end-to-end Node and DiskPool deletion APIs across REST and gRPC, introducing crash-safe state machines and purge workflows that automate cleanup and reduce manual intervention. Leveraging Rust, Kubernetes, and OpenAPI, Niladri designed reconciler-based logic to ensure reliable state transitions and error handling during node and pool purges. His work included plugin-level deletion enhancements, improved test automation, and internal refactors, resulting in a scalable, maintainable system that streamlines decommissioning and strengthens operational reliability for cloud-native storage environments.
April 2026 (openebs/mayastor-control-plane) delivered end-to-end Node Deletion API integration across REST and gRPC, implemented Node Purge lifecycle (offline/cordoned validation, crash-safe Purging state, auto-cordon of pools, and per-pool purge delegation with nexus cleanup), and enhanced pool/plugin deletion workflows with improved API exposure and error handling. Also contributed significant internal reliability improvements and test stability efforts (refactors, requeue-based reconciliation, and test hardening). Business impact: enables safe, automated node/resource decommissioning with consistent behavior across interfaces, reduces manual intervention, and improves cluster resilience and cleanup accuracy. The work lays a robust foundation for scalable lifecycle management as the system grows. Technologies/skills demonstrated: REST and gRPC API design and integration, OpenAPI spec evolution, protobuf-based data types, crash-safe state machines and reconciler patterns, auto-cordon and resource disowning logic, plugin-level deletion enhancements, and focused internal refactors and test automation.
