Thanks @jorgecarleitao for being patient with me and updating the test :) > IMO the reason we cannot test it is because the current C++ does not write date64 as a 64 bit int in parquet, and thus we have no way of constructing a 64int column in parquet with data type date64. This is the part I don't understand. Since Parquet only support annotate DATE to int32 type according to its specification, how can you write a date64 as int64 in Parquet: it has to be annotated with something to indicate it is a DATE type so that when Arrow converts a int64 type from Parquet it knows what type in Arrow it should go to (int64, decimal, timestamp, etc). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
