Pega 8.x Cache Management

Hi

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.

Thanks in advance to anybody that is able to share related information.

@ArunS775 I have had a look to see if I could find a definitive document but indeed nothing exists that brings all topics together in one article the way it was documented for version 7.x

I found the following forum question and our SME recommendations in How to clear caches in 8.1.

Go to Admin Studio->Resources->APIs

Under System Management → Cache

Service APi we can use same for clearing cache

Also see Pega 8.X Cache Settings , Preassembling rules in an application and Cache Exceeds Limit.

Regarding system performance, perhaps this might help you:

Wiki Performance Checklist

Configuring key cache settings

Does this help in some way to answer your question?

@MarijeSchillern Thank you! Just noticed my query have been answered. A suggestion is that it would be great to have the caching part documented in one pack/single reference point like it used to be for version 6.x.

@Arun_V_S many thanks for your idea.

If the information detailed in Changing the default keystore caching settings Pega 8.X Cache Settings , Preassembling rules in an application , Savable data pages and Cache Exceeds Limit. could be improved, please could you use the ‘Feedback’ button on one of those articles in order to put forward your suggestion?

That is the the most direct way to contact our documentation team for the relevant subjects.

Note: Two enhancement requests exist for this in case you wish to discuss these further with your Pega AE:
