--------------------------------------
Summary: Create a PTransform that reads data from BigQuery in
Python SDK
Key: BEAM-8283
URL: https://issues.apache.org/jira/browse/BEAM-8283
Project: Beam
Issue Type: Improvement
Components: io-py-gcp
Reporter: Kamil Wasilewski
Assignee: Kamil Wasilewski
ATM `BigQuerySource` in Python SDK can only be used by Dataflow runner. Because
of this it's impossible to read data from BigQuery on portable runners, such as
Flink.
The goal is to add a transform, that follows BQ source implementation in
Java[1]: use a BigQuery export job to take a snapshot of the table on GCS, and
then read from each produced file.
