Worked on backend development for the wazuh-indexer repository, delivering a performance optimization feature focused on dynamic system configuration. Implemented a dynamic global maxMergeAtOnce setting in Java, increasing the default value from 10 to 30 to allow more parallel segment merging during indexing. This adjustment aimed to reduce index merge latency and improve throughput under heavy load, resulting in faster data availability and enhanced search performance. The work included updating the changelog, adding integration tests in Markdown, and modifying the core index service to support runtime configuration changes without redeployment. All changes were validated through continuous integration and merged to main.
