In March 2025, Yanglei enhanced the crossoverJie/starrocks repository by extending DateUtils to support parsing 14-character date-time strings in the YYYYMMDDHHMMSS format. Using Java and SQL, Yanglei introduced the DATE_TIME_S_FORMATTER_UNIX formatter and updated probeFormat to handle unsigned second-level timestamps, addressing the need for precise, compact date keys in partitioning and query planning. Comprehensive unit tests, including DateUtilsTest and PartitionUtilTest, were added to ensure accurate parsing and partition-key conversion. This backend development work improved data ingestion reliability and enabled more efficient partition pruning for time-series workloads, reducing manual data preparation and supporting cleaner, faster analytics.
