[jira] [Created] (BEAM-8910) Use AVRO instead of JSON in BigQuery bounded source.

Kamil Wasilewski created BEAM-8910:
--------------------------------------

             Summary: Use AVRO instead of JSON in BigQuery bounded source.
                 Key: BEAM-8910
                 URL: https://issues.apache.org/jira/browse/BEAM-8910
             Project: Beam
          Issue Type: Improvement
          Components: sdk-py-core
            Reporter: Kamil Wasilewski


The proposed BigQuery bounded source in Python SDK (see PR: [https://github.com/apache/beam/pull/9772)] uses a BigQuery export job to take a snapshot of the table and read from each produced JSON file. A performance improvement can be gain by switching to AVRO instead.
