Atri worked on the wazuh/wazuh-indexer repository, delivering three core features over two months to enhance data routing and search extensibility. He implemented hierarchical and ACL-aware routing processors for both ingest and search pipelines, using Java and Groovy to enable deterministic document co-location based on hierarchical paths or ACL metadata. His approach leveraged MurmurHash3-based routing to maintain shard alignment, reducing cross-shard traffic and improving query performance in multi-tenant environments. Atri also introduced extensible QueryPhase hooks for plugins, supporting advanced search features. The work demonstrated depth in backend development, distributed systems, and test-driven design, addressing scalability and maintainability for complex data workloads.

August 2025 monthly summary for wazuh/wazuh-indexer. Focused on architectural enhancements to improve multi-tenant data locality, routing efficiency, and extensibility of the search pipeline. Delivered two major features with strong testing coverage and clear business value: ACL-Aware Routing for Ingest and Search, and QueryPhase Extension Points for Plugins. No high-severity bug fixes recorded this month; emphasis was on delivering reliable, test-covered capabilities and laying the groundwork for future plugin-driven growth.

July 2025 monthly summary for wazuh/wazuh-indexer. Delivered Hierarchical routing processors for ingest and search pipelines, enabling co-location of documents based on hierarchical paths and configurable routing semantics. Implemented HierarchicalRoutingProcessor (ingest) and HierarchicalRoutingSearchProcessor (search) with consistent MurmurHash3-based routing to ensure documents and queries align across stages. Configurable anchor depth, path separators, and field mapping allow tuning for various hierarchies, reducing search latency and cross-shard traffic. The work aligns with performance and scalability goals for hierarchical data indexing.
