Varun Bansal delivered a performance optimization for the wazuh-indexer repository by implementing a dynamic global maxMergeAtOnce setting, increasing the default from 10 to 30 to enable more parallel segment merging. Using Java and leveraging backend development and system configuration skills, Varun updated the core index service to support runtime adjustments without redeployment. The work included changelog updates and integration tests written in Java and Markdown to ensure reliability and maintainability. This feature reduced index merge latency and improved throughput under heavy indexing loads, resulting in faster data availability and search performance. All changes were validated in CI and merged to main.
