| This is CoGroupByKey load test with Synthetic Source. Besides of the standard |
| input options there are additional options: |
| * project (optional) - the gcp project in case of saving |
| metrics in Big Query (in case of Dataflow Runner |
| it is required to specify project of runner), |
| * publish_to_big_query - if metrics should be published in big query, |
| * metrics_namespace (optional) - name of BigQuery dataset where metrics |
| will be stored, |
| * metrics_table (optional) - name of BigQuery table where metrics |
| will be stored, |
| * input_options - options for Synthetic Sources, |
| * co_input_options - options for Synthetic Sources, |
| * iterations - number of reiterations over per-key-grouped values to perform |
| (default: 1). |
| |
