PROFILE

Alper Kocatas

Contributed to database reliability and observability by delivering targeted backend enhancements in both yugabyte/yugabyte-db and citusdata/citus. Addressed audit logging robustness in yugabyte/yugabyte-db by refining the PGAudit stack handling logic using C, ensuring that CALL statements no longer trigger false stack-not-empty errors during concurrent SQL execution. In citusdata/citus, implemented a new SQL view, citus_nodes, within pg_catalog to expose per-node details such as name, port, role, and active status, accompanied by comprehensive test coverage for public accessibility. Demonstrated expertise in C, SQL, and database auditing, focusing on production-grade reliability and improved diagnostics for distributed database environments.

May 2025 – Focused feature delivery and test coverage for observability and node diagnostics in citusdata/citus. Implemented a new SQL view citus_nodes in pg_catalog to surface per-node information (name, port, role, active status) and added tests to ensure visibility and public accessibility. This enhances observability for multi-node deployments, enables faster diagnostics, and informs capacity planning. Commit 088ba7505798acbfca6334cc2645c93215ab14d8 ('Add citus_nodes view (#7968)').

February 2025 monthly summary for yugabyte/yugabyte-db focusing on reliability improvements and security/audit integrity. Delivered targeted fix to PGAudit stack handling to prevent false stack-not-empty errors when a CALL statement is executed while another command is on the stack. The change is encapsulated in the commit that adds an exception for CALL statements to the stack check logic, enhancing the robustness of audit logging in mixed SQL workloads.
