Over a two-month period, contributed to the datametica/calcite repository by delivering two features focused on SQL dialect compatibility and regex processing. Developed PostgreSQL TOP clause support with PERCENT and WITH TIES, including comprehensive regression tests to ensure correct behavior in offset and fetch scenarios, thereby improving cross-dialect query portability between PostgreSQL and AlloyDB. Additionally, enhanced BigQuery’s REGEXP_CONTAINS function by implementing start and end anchor support to align with Teradata’s REGEXP_SIMILAR, reducing the need for user workarounds. The work leveraged Java, SQL, and unit testing, emphasizing robust data processing and database management across multiple analytics platforms.

Apr 1, 2026April 2026 monthly summary focused on delivering PostgreSQL TOP and WITH TIES support in the Calcite PostgreSQL dialect, along with comprehensive tests to ensure correct behavior of WITH TIES in offset/fetch scenarios. The work also aligns with cross-dialect needs (notably AlloyDB) to improve portability of TOP-based queries across PostgreSQL-compatible engines.
