Add Parquet Time32/64 Support by Converting to DateTime64
Add support to Parquet Time32/64 by converting it into DateTime64. Parquet time32/64 represents time elapsed since midnight, while DateTime32/64 represents an actual unix timestamp. Conversion simply offsets from 0. #41333 (Arthur Passos).Why it matters
Parquettime32 and time64 types represent time elapsed since midnight, which differs from ClickHouse DateTime32/DateTime64 representing actual UNIX timestamps. This feature solves the incompatibility by converting Parquet time values with an offset from zero, enabling accurate and seamless ingestion of Parquet time data into ClickHouse.How to use it
When importing Parquet files containingtime32 or time64 columns, these are automatically converted into ClickHouse DateTime64 columns without additional user action.
