Shobhit Kumar enhanced observability in the yugabyte/yugabyte-db repository by implementing Active Session History User ID Tracking. He added a ysql_userid column to the ASH system, updating both the schema and internal data structures to enable per-user query attribution. This work involved modifying ASH sampling logic and designing new mechanisms for storing user IDs, which supports more effective troubleshooting and performance analysis. Using C++, SQL, and his knowledge of database internals, Shobhit laid the foundation for user-based analytics and capacity planning. His contributions improved the system’s ability to diagnose issues and provided deeper insights into query performance by user.
