PROFILE
Ch Chethan Reddy
During two months contributing to linkedin/ambry, Chereddy developed foundational features to improve storage reliability and cluster resilience. He introduced new interfaces for disruption management and refactored disk space handling, integrating DiskSpaceAllocator with Log and BlobStoreCompactor to enhance data replica processing. In May, Chereddy extended DiskSpaceAllocator to FileStore, enabling pre-allocation and dynamic file management with robust error handling and comprehensive unit tests. He also addressed startup synchronization issues for node onboarding by implementing concurrency controls using latches. Working primarily in Java, Chereddy demonstrated depth in backend development, distributed systems, and system design, delivering maintainable solutions that strengthened storage predictability and reliability.

May 1, 2025May 2025 performance summary for linkedin/ambry: Focused on storage efficiency, cluster reliability, and test stability. Delivered DiskSpaceAllocator for FileStore enabling pre-allocation and on-demand management with allocate and free APIs, accompanied by robust error handling and comprehensive unit tests (commit 28c9d1bcb4c2279a4a6007781cf4e42657aa61f9). Fixed startup synchronization for node addition by introducing latches to ensure data node configuration and listeners are registered before state transitions, with improvements to test stability and startup error handling (commit 5e203d836c16cd636cf1a78f19dd5cadfe2c17bd). Business impact includes improved storage predictability and capacity planning, faster and more reliable node onboarding, and stronger overall system resilience. Demonstrated skills include distributed systems design, resource management, concurrency control, unit testing, and robust error handling.
