--------------------------------
Summary: Write bytes to BigQuery in Python 3
Key: BEAM-6769
URL: https://issues.apache.org/jira/browse/BEAM-6769
Project: Beam
Issue Type: Sub-task
Components: sdk-py-core
Reporter: Juta Staes
Assignee: Juta Staes
In Python 2 you could write bytes data to BigQuery. This is tested in
[https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/gcp/big_query_query_to_table_it_test.py#L186]
Python 3 does not support
{noformat}
json.dumps({'test': b'test'}){noformat}
which is used to encode the data in
[https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/gcp/bigquery_tools.py#L959]
How should writing bytes to BigQuery be handled in Python 3?
* Forbid writing bytes into BigQuery on Python 3
* Guess the encoding (utf-8?)
* Pass the encoding to BigQuery
