June 2026 Velox (facebookincubator/velox) delivered notable enhancements to RPC batch-mode testing and addressed critical concurrency and correctness issues in the RPCOperator BATCH path. The work improved test coverage, reliability, and end-to-end validation for batch dispatch scenarios, directly strengthening system robustness and developer velocity.

June 2025: Backed out the previous JDBC write mappings for data types in prestodb/presto and replaced them with direct SQL type mapping to simplify JDBC connector data type handling. This change reduces complexity, lowers maintenance burden, and improves compatibility and stability for JDBC integrations.

March 2025 highlights: Delivered a new parse_duration function for Velox's Presto SQL dialect, enabling direct parsing of duration strings (value + unit) into milliseconds. The function supports multiple time units and includes robust error checking for invalid formats and out-of-range values. This feature reduces external parsing work, streamlines time-based querying, and aligns Velox with Presto semantics. Technical work centered on a single commit (17d5f836cc31f35defc27a890c0703c581811333) as part of PR #12500 in IBM/velox.
