PROFILE
Houston Putman
Houston contributed to the apache/solr repository by engineering robust backend features and stability improvements over ten months. He migrated Solr’s ZooKeeper management to Apache Curator, enhancing reliability and simplifying distributed coordination. Houston upgraded build systems, refactored error handling, and introduced caching strategies to optimize cluster state retrieval and reduce latency. He implemented host-aware replica routing and improved compatibility with evolving Java versions, addressing startup and security concerns. Using Java, Gradle, and Shell scripting, he also expanded test automation and documentation, ensuring maintainable releases. His work demonstrated depth in distributed systems, concurrency, and performance tuning, directly improving Solr’s operational resilience.

Sep 1, 2025September 2025 performance-focused delivery for apache/solr. Key features delivered include cluster state retrieval performance improvements via Remote Proxy caching and background prefetching of liveNodes to reduce latency spikes, and host-based replica routing (shards.preference=replica.location:host) to cut intra-host network traffic. Major bug fix includes Java 24+ startup compatibility by conditionally disabling the Security Manager and updating docs. Collectively, these changes improve startup reliability, reduce latency spikes, and optimize network utilization in multi-instance deployments. Demonstrated skills include caching strategies, background prefetching, conditional Java compatibility, and host-aware routing, delivering business value through faster cluster state access and more efficient query routing.

Oct 1, 2024In October 2024, delivered a reliability-focused feature for Solr by migrating ZooKeeper management to Apache Curator. Replaced direct ZooKeeper client usage with Curator across Solr components, added Curator as a dependency, and refactored code paths to leverage Curator for robust ZooKeeper operations. This simplification reduces operational risk during config changes and leadership events, improving overall system stability and maintainability. The work aligns with SOLR-16116 and was committed as e5d15cc84f8ad790e1b6c901d74bd86b7c1de17c (commit #760).
