> 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.

> 2. sin-based.
