Contributed to the apache/cassandra repository by developing SSTable Read Logging for Performance Monitoring, a feature that enhances observability of read-heavy workloads. This work introduced a dedicated logging mechanism in Java to track queries accessing more than a configured number of SSTables, providing deeper insight into query patterns and potential performance bottlenecks. The implementation focused on backend development and database management, supporting production troubleshooting and performance tuning in large-scale deployments. By enabling more granular monitoring and faster diagnosis of issues, the feature improved reliability and operability for Cassandra users, laying the foundation for future metrics and optimization efforts in distributed systems.
