Decode Date32 arrow type in DataFrame #7261
Description
Is your feature request related to a problem? Please describe.
At the moment, it looks like it's not possible to read RecordBatches of Date32s:
using Apache.Arrow; using Microsoft.Data.Analysis; var batch = new RecordBatch.Builder() .Append("DateColumn", false, new Date32Array.Builder().AppendRange(Enumerable.Repeat(DateTime.Now, 10)).Build()) .Build(); DataFrame.FromArrowRecordBatch(batch);gives:
Unhandled exception. System.NotImplementedException: date32 at Microsoft.Data.Analysis.DataFrame.AppendDataFrameColumnFromArrowArray(Field field, IArrowArray arrowArray, DataFrame ret, String fieldNamePrefix) at Microsoft.Data.Analysis.DataFrame.FromArrowRecordBatch(RecordBatch recordBatch) at Program.<Main>$(String[] args)
