eZ Publish Knowledge Series: «Stale Cache» or «How caches in eZ Publish 4.1 are handled in a smarter way»

Introduction

This article describes in detail the principles and functions of the new cache system present in eZ Publish 4.1. Overall the idea can be summarised as follows: instead of deleting cache elements and then regenerate them across concurrent requests, the logic is reversed to a refresh algorithm. Basically a cache element will be marked as invalid but not deleted until a new version is ready. During the generation of the new cache element, the old version will still be served until it is ready.
