ProCache Sync

Synchronises ProCache clearing across a multi-instance environment.


The main purpose of this module is to allow ProCache to be used in an auto-scaling multi-instance environment.

How it works

When a page is saved and cache clearing is triggered, the data (methods / arguments) associated with that clear are saved to the database. ProCacheSync runs a check every 30 seconds to look for records in the database since ProCache was last cleared. If it finds any it processes them as ProCache would. Any records it finds will have been generated by a clear on another server instance, thus enabling multiple instances of ProCache to stay approximately synchronous.
