How to trigger DSP cache invalidation and reload?

Question

We have a scheduled job to update the database nightly. I used DSP caching to increase performance since the data only changes during the nightly updates.
Does anyone know how can I trigger the DSP cache invalidation and reload the updated data to DSP cache once the data loading is completed on the database server? (The database is hosted on a different server than DSP.)
Thanks in advance!

Bypassing the Data Cache When Using the Mediator API
Data retrieved by data service functions can be cached for quick access. This is known as a data caching. (See Configuring the Query Results Cache, in the DSP Administration Guide for details.) Assuming the data changes infrequently, it's likely that you'll want to use the cache capability.
You can bypass the data cache by passing the GET_CURRENT_DATA attribute within a function call, as shown in Listing 3-7. GET_CURRENT_DATA returns a Boolean value. As a by-product, the cache is also refreshed.
Listing 3-7 Cache Bypass Example When Using Mediator API
dataServices.customermanagement.CustomerProfile customerProfileDS =
customerDS=dataServices.customermanagement.CustomerProfile.getInstance(ctx,appName);RequestConfig
config = new
RequestConfig();attr.enableFeature(RequestConfig.GET_CURRENT_DATA);CustomerProfileDocument
customerProfileDoc customerPlofileDS.CustomerProfile(params,config);
