PROFILE
Harsh Kothari
Over a two-month period, contributed three backend features to the wazuh-indexer repository, focusing on performance and reliability in distributed systems. Developed an Auto Force Merge Manager that automates index segment optimization during hot-to-warm migrations, using configurable triggers and system-condition checks to balance resource usage and query latency. Enhanced resource monitoring by replacing CPU load average logic with an AverageTracker and introducing default thresholds for CPU, JVM, and disk usage. Accelerated node startup by parallelizing file cache loading across directories with Java’s ForkJoinPool. Work demonstrated expertise in Java, concurrency, file I/O, and system optimization, addressing complex backend challenges.

Jul 1, 2025July 2025: Delivered two critical performance and reliability enhancements for wazuh/wazuh-indexer. Implemented Auto-force Merge: Resource Monitoring Enhancements to improve shard-merge decisions by replacing the CPU load average logic with an AverageTracker-based approach, adding default thresholds for CPU, JVM, and disk usage, and adjusting the merge delay between shards for more accurate, reliable auto-merge behavior. Added Parallel File Cache Loading for Faster Node Startup to accelerate startup and cache restoration by parallelizing file cache loading across multiple directories using ForkJoinPool, with targeted refactors for parallel I/O.
