PROFILE
Alper Kocatas
Alper Kocatas contributed to database reliability and observability by developing targeted features and fixes in open-source repositories. In yugabyte/yugabyte-db, he improved audit logging robustness by refining the pgaudit stack handling in C, ensuring that CALL statements no longer triggered false stack-not-empty errors during concurrent SQL execution. Later, in citusdata/citus, he implemented a new citus_nodes SQL view within pg_catalog using SQL and backend development skills, exposing per-node details to enhance diagnostics and capacity planning for distributed deployments. His work demonstrated a strong grasp of PostgreSQL internals, database auditing, and test-driven development, delivering focused solutions to production challenges.

May 1, 2025May 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)').
