PROFILE

Shapatin Artem

Worked on stabilizing and enhancing database testing infrastructure across GreengageDB/greengage and arenadata/gpdb repositories. Addressed flaky full-text search tests by introducing a synchronization mechanism in C, improving determinism and reliability for GreengageDB/greengage. In arenadata/gpdb, enabled Minirepro tests by updating Python-based test automation, increasing coverage for critical query paths and reducing deployment risk. Also implemented a Python 3 compatibility patch for the gp_disk_free external web table, updating legacy print statements to ensure smooth migration and reduce technical debt. Demonstrated skills in debugging, Python programming, SQL scripting, and behavior-driven development, with a focus on robust, maintainable test systems.

March 2026 monthly summary for arenadata/gpdb: GP Toolkit gp_disk_free external web table Python 3 compatibility patch implemented to align with the Python 3 migration plan. Replaced Python 2 print usage with a cross-version print() to ensure correct behavior across environments and reduce risk during migrations. The change improves stability of external web tables and reduces technical debt related to catalog definitions awaiting migration.

February 2026: focused on strengthening test coverage in arenadata/gpdb by enabling Minirepro tests and validating essential query-related database objects. Implemented via removing the skip tag from the minirepro feature, enabling execution and ensuring validation of core objects. No major bugs fixed this month in this repo; the primary value was improved reliability and faster feedback through CI-driven test automation. Overall impact: reduced risk of regression in production deployments and improved confidence in query performance paths. Technologies include Git, CI/test automation, and minirepro testing.

September 2025 — GreengageDB/greengage: Focused on stabilizing the test suite for the full-text search component. Implemented a waiting/synchronization mechanism to ensure injected faults are fully processed before subsequent commands, addressing flaky behavior and improving determinism of tests. Changes touched postmaster.c and related test files. Commit: 1c9963eb9b97c7778aaf2c2f80f12045c26da121. Impact: Reduced test flakiness, enabling faster iteration and higher confidence in FTS work.
