2025-10 Monthly Summary: Delivered Table Metadata V3 support for apache/iceberg-go, enabling V3-compatible metadata parsing and validation. This work improves compatibility with newer Iceberg versions, boosts metadata reliability, and sets the foundation for future metadata feature work in the repo.

September 2025: Delivered two high-impact features for apache/iceberg-go that drive data hygiene, governance, and compatibility with Iceberg v3. 1) Delete Orphan Files maintenance utility with dry-run, age and concurrency controls, plus tests. 2) Iceberg Manifest v3 support, including NewManifestListWriterV3 with metadata fields and validation, plus tests. These initiatives reduce storage waste, improve data reliability, and position the project for Iceberg 3 deployments. Skills demonstrated: Go, testing (unit/integration), concurrency, and metadata validation.

July 2025 monthly summary for ankane/iceberg-go: Delivered a major Iceberg CLI enhancement enabling detailed table creation via CreateTableOpt with properties, partition specs, and sort orders. This work improves automation, reproducibility, and configurability, reducing manual steps and enabling more precise deployments.

June 2025: Delivered key SQL catalog enhancements and REST authentication improvements in iceberg-go, focusing on security, data modeling capabilities, and test reliability. The work lays groundwork for richer data modeling with views and strengthens CI confidence through integration tests.

April 2025 monthly summary for ankane/iceberg-go focused on enabling programmatic view management via the REST catalog. Implemented CreateView in the REST catalog, providing end-to-end support to create views with specified schemas, SQL, and properties. Added payload construction, error handling for common scenarios (view already exists, namespace not found), and accompanying tests. The work is captured in commit cdb568df61c955c5b4ef2648086671955fe1b5e7 with message "feat (catalog/rest): Add create view for rest catalog (#376)".

March 2025 focused on hardening quality gates, expanding Glue catalog capabilities for Iceberg, and aligning catalog actions across systems. Deliveries emphasize safer deployments, robust table management, and improved test coverage, enabling faster, more reliable data lake operations and easier onboarding for new catalogs.

February 2025: Delivered key REST catalog enhancements and cross-catalog capabilities for ankane/iceberg-go, with a focus on reliability, scalability, and developer productivity. Implemented REST catalog view management (list, drop, exists) and expanded test coverage for RegisterTable to reduce REST regressions. Introduced paginated ListTables responses across catalog types and added Glue-based namespace validation via CheckNamespaceExists. These changes strengthen multi-catalog workflows, improve API reliability, and enable safer deployments. Notable outcomes include improved CI/test coverage and clearer API surfaces for customers with multi-catalog setups.

January 2025 monthly summary focused on delivering robust catalog management capabilities in ankane/iceberg-go and expanding REST visibility for existence checks. Achievements center on improving reliability, test coverage, and API consistency, driving reduced risk in catalog usage and faster issue detection.
