Set the size of cached posts from other pods?

In the FAQ,

Can the administrators of other pods see my information?
Once you are sharing with someone on another pod, any posts you share with them and a copy of your profile data are stored (cached) on their pod, and are accessible to that pod’s database administrator. When you delete a post or profile data it is deleted from your pod and any other pods where it had previously been stored.

I’m wondering that, is this cache size configurable for a pod administrator. If yes, can someone point me to the documentation? Thanks!

This isn’t a cache, other pods store all information they need to show it to their users.

Cool, thanks. Do you think it’ll be better to delete the word cached from FAQ?

Yes, I just removed it.
