Doctrine offers Filesystem cache too. I looked at source code of doctrine-cache-bundle of my vendor and see its systax here is file_system, it has “directory” element too. But how to define it in config.yml? Please see the source code of that bundle.
That way seems to be for general use of cache system. I want to use cache for metadata and query, to do so I think I should go with the way you gave the link in your earlier reply on symfony site. As you see in your latter link there is file_system too, but I get error for “directory” element. How should I use it?
