> In some scenarios, we need to simulate flow changes in the production
> environment. The current DATAGEN feature only supports data generation at a
> constant rate. We try to simulate increments of flow using batch jobs, but
> the production rate is not smooth, so I suggest that we can support sin-based
> data generation in order to get smooth changes.
> 1. add another batch job to simulate increments of flow.
