 * The test results for these load tests reside in BigQuery in the load_test/load_test_PRs table of the
 * apache-beam-testing project. A dashboard is available here:
 * https://apache-beam-testing.appspot.com/explore?dashboard=5751884853805056

 * For example:
 *   SELECT
 * 	  timestamp, value
 *   FROM
 * 	  apache-beam-testing.load_test_PRs.python_flink_batch_pardo_1
 *   ORDER BY
 *    timestamp
 *
 * The following query has been been used to visualize the checkpoint results of python_flink_streaming_pardo_6:
 *   Select timestamp, min, sum/count as avg, max
 *   FROM (
 *     SELECT
 *       timestamp,
 *       MAX(IF(metric LIKE "%\\_min\\_%", value, null)) min,
