Description

For background BigQuery is using AVRO decimal to store internal NUMERIC fields in its https://cloud.google.com/bigquery/docs/reference/storage#avro_schema_details API

TensorFlow IO is a project to import data from BigQuery into TensorFlow dataset.

https://github.com/tensorflow/io/issues/875

Currently there is no straightforward way to deserialize NUMERIC fields.

It would also be nice to have a function to convert Decimal to C++ double.
