Apr 1, 2026Month: 2026-04. Delivered MongoDB views querying in Presto's MongoDB connector, with view-type handling, MongoSession updates to distinguish between collections and views, and tests validating view queries. Included fix: Allow view querying with Mongo connector (#26995). This work expands analytics reach by enabling SQL access to MongoDB views (virtual collections) without data duplication, improving data discoverability and BI pipeline efficiency.

Feb 1, 2026February 2026: Focused on quality and correctness in prestodb/presto by hardening null-safety in the UtilizedColumnsAnalyzer and improving user feedback for CREATE TABLE IF NOT EXISTS. Delivered a targeted fix to prevent potential NullPointer exceptions when processing SELECT items and introduced a clear user-facing warning when CREATE TABLE IF NOT EXISTS would no-op due to an existing table, reducing unnecessary work and speeding up feedback loops for users. The changes improve runtime robustness and user experience while aligning with codebase reliability goals.
