During March 2025, contributed a new parse_duration function to the IBM/velox repository, enhancing the Presto SQL dialect by enabling direct parsing of duration strings into milliseconds. This backend feature was implemented in C++ and focused on supporting multiple time units while incorporating robust validation to handle invalid formats and out-of-range values. By streamlining the conversion of string-based durations within SQL queries, the work reduced the need for external parsing and improved query reliability. The technical approach centered on database function development and SQL integration, aligning Velox more closely with Presto semantics and supporting more efficient time-based querying workflows.
