----------------------------------

We are facing a problem when reading from BigQuery and relying on Beam Schema for the type BigDecimal.

>            Reporter: Rui Wang
>            Priority: Major

> Right now BigQueryIO returns avro format data and Beam SQL parses it and convert to Row. More specifically, decimal value is saved into HeapByteBuffer
>  
> Need to investigate what's the way to convert from byte buffer to BigDecimal.
