System Information (please complete the following information):

  • .Net Framework 4.7.2

Describe the bug
I am getting the below exception

Unhandled exception. System.NotImplementedException: decimal128
at Microsoft.Data.Analysis.DataFrame.AppendDataFrameColumnFromArrowArray(Field field, IArrowArray arrowArray, DataFrame ret, String fieldNamePrefix)
at Microsoft.Data.Analysis.DataFrame.FromArrowRecordBatch(RecordBatch recordBatch)
at Program.

To Reproduce
Take a .arrow file with one column of type Apache.Arrow.Types.Decimal128Type
var dataframe = DataFrame.FromArrowRecordBatch(recordBatch);
It will throw above exception

Expected behavior
The record batch should transform to DataFrame with appropriate type to handle decimal128
