Abstract

A cache and method of caching for a database are provided, in which the cache and the database are in the same state.

If there are multiple users and/or instances, the cache may be updated for all users and/or instances by determining whether all changes are to be committed, in which case the changes are pushed to all users and/or instances.

responsive to a determination that the request is initiated by…
