[jira] [Created] (BEAM-6931) Remove destination tables in BigQueryStorageQuerySource

Kenneth Jung created BEAM-6931:
----------------------------------

             Summary: Remove destination tables in BigQueryStorageQuerySource
                 Key: BEAM-6931
                 URL: https://issues.apache.org/jira/browse/BEAM-6931
             Project: Beam
          Issue Type: Improvement
          Components: io-java-gcp
            Reporter: Kenneth Jung


In BigQueryStorageQuerySource, the results of a BigQuery query are written to a (named) temporary destination table rather than to an anonymous table since the BigQuery storage API can't currently read from all anonymous tables. When this API restriction is removed, then the BigQueryStorageQuerySource can start reading directly from anonymous result tables and most of the logic related to template compatibility and temporary dataset cleanup can be removed.
