> > The overflow happens because Datafusion treats underlying i64 as nanoseconds which is obviously not big enough. > > I'm confused by this statement, DataFusion follows the arrow data model which has various different timestamp precisions. There is no hard coded mapping to nanoseconds, rather anything from seconds to nanoseconds is supported Right, I can see there are bunch of hardcodes to nanoseconds, like cast from string to timestamp will come as nanoseconds, read from parquet, coercions, etc. -- This is an automated message from the Apache Git Service.
