Adding Scenarios

All of the named scenarios that are bundled with NoSQLBench are simply named yaml files with scenarios included.

If you are a developer and want to add one of these, you can submit a pull request to the main project. However, to be accepted, any named scenario should follow all the conventions described in the main Designing Workloads documentation, including naming, tagging, and default values.

If you are not a developer, and you have come up with a workload that you'd like to make part of the standard NoSQLBench distribution, you can add it to an issue on the main issue tracker.
