I wonder if there is a reference guide on the topic to understand cache and cache management in Pega 8.x. I could not find materials on this subject specifically for Pega 8.x. Are there any caching advancements in Pega 8.x or it follows the same approach as Pega 7.x? Given the subject is a key topic, I am little surprised my search did not yield relevant results or perhaps I am not searching right. Developers that have worked in Pega 7.x know the various caches the platform uses to optimize System performance but has anything changed in Pega 8.x? The following link provides a good overview of various caches in Pega 7.x.
Also, is there a documentation for all the API services that comes with the product? This is to understand the data elements in API response body and what they mean, especially for those System Management related services. The following link just lists what roles are required to view and test run the APIs.
