• Architected and implemented Dice-DB store as a multi-shard, shared-nothing architecture resulting in 5x increase in maximum supported keys on a single node while ensuring sub-millisecond latency.
• Architected Dice-DB to optimally leverage modern multi-core server hardware by implementing asynchronous, non-blocking network I/O and minimizing resource contention through modern concurrency constructs. This resulted in achieving a 10x increase in peak throughput and a 4x increase in average throughput compared to Redis.
• Designed and architected real-time reactive watch APIs in DiceDB, transforming it into a truly real-time reactive database. This innovation enabled clients to adopt an efficient push-based model, improving responsiveness by upto 3 times.
• Implemented extensible and adaptive eviction framework enabling integration of different eviction policies into DiceDB.
• Designing an extremely efficient, fast and adaptive cache implementation that ensures near zero dynamic memory allocations and minimal lock contention while iterating through the store entries. This would ensure extremely efficient scanning, eviction and snap-shotting implementations and extremely predictable system response time.
