      Work Description: apilloud opened a new pull request #13184:
URL: https://github.com/apache/beam/pull/13184


   The query is somewhat complex to avoid reading data. On `bigquery-public-data.samples.github_nested` this consumed 0.02 seconds and 0 bytes shuffle, vs 'SELECT count(*)' consuming 1 second and 72 bytes shuffle.

> BigQueryServicesImpl.isTableEmpty currently uses tabledata.list API, which can return a large number of rows and stale results. This has resulted in flaky tests inside google. The BigQuery team suggests this can be made more reliable if it used the jobs.query API instead.
