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.

We are working on it currently. This happened when migrating the articles, as you may expect.

Thanks for the feedback!

Hi John,

Unfortunately not, this feature is present from eZ Publish 4.1 on. If migration is an option, you should make your way there.

Cheers !
