Assuming you meant the maximal recommended frequency, the short answer is as often as you want...however, there are considerations:
For apps that are display-only, you can run them infinitely on loop without issues as long as the server has the resources required to do so.
For apps that are mostly for display and mostly do not require selections or multiple steps, perhaps once every few minutes would be reasonable. This is also true for apps where the primary usage is to export data.
For apps that people use for actual analytics, it's a tradeoff between constantly refreshing their session with the new data and getting fresh data. I've never gone below ten minutes for one of these. The more complex the usage, the longer you'll want the refresh intervals to be - for a proper analytics app I wouldn't want to go lower than once an hour.
If you need anything that is lower than these guidelines, you can always consider using ODAG to pull the data in real-time and keep it there until the user refreshes it.

Qlik Replicate is a data replication Tool which do the near Realtime data replication between verity of Database.
Full load or Initial load require to provide Exact data on both sides. so that DML processed on the target side without any issue and Data is available on the target Side in real time.
Full Load required during initial setup and Due to some unforeseen issue if target table become out of sync, then Full load is required sync'ing prior to CDC.
As er your Use case. you can initiate Full whenever you want so that can be decided based upon business requirements and all.
