Design for dealing with the large amount of outbound rest API calls
We are building an application where we need to get the data from the external system required for case processing. To get the data, we need to call two rest API.
1: API -1 gives 1 million or more of records, but we are interested only in one field of these records.
2: API-2 is a call for these 1- Million records separately, i.e. (the same API needs to call for 1 million times ). Again, we are interested in the 1 or 2 fields.
This data can not be cached in pega for a long time. Data get updated in the external system at least close to real-time.
Performance and close to real-time calls are the main factors to consider while designing the solution.
