Understanding this use vs regular Drupal 7 cache, apc, memcache, and filecache modules?

Those modules are cache backends which allow to cache things in a place other than the default databaes backend.

This module *uses* one of those backends to cache entities, like nodes or users.

Exactly

And how to tell Entity Cache to use Filecache instead of Database Cache? Something like that?

  $conf['cache_class_entity_cache'] = 'DrupalFileCache';

@Wolfgang Reszel, I don't have an entity_cache table in my database, I would double check that. I think you need to enable each individual entity cache bin-- for example, here's how I use Entity Cache and APC together:

$conf['cache_class_cache_entity_file'] = 'DrupalAPCCache';
$conf['cache_class_cache_entity_node'] = 'DrupalAPCCache';
$conf['cache_class_cache_entity_taxonomy_term'] = 'DrupalAPCCache';
$conf['cache_class_cache_entity_taxonomy_vocabulary'] = 'DrupalAPCCache';

Thanks for the help. It seems to work.

hi

Please need some extra clarification
By default Filecache module suggest using $conf['cache_default_class'] = 'DrupalFileCache'; WHICH will already offload all bins to location..

How to THEN use together with entity cache

Hi @Berdir,
Regular drupal 7 cache, memchae, apc and file cache works in different way. Drupal 7 cache works from db level. It stored all cache data in cache tables in blob format and retrieve as required. Now memcache is a memory level cache mechanism. Apc works in php file level and it takes php codes in executable and store in cache so that disk I/O and other server overhead will be reduced. You can get an overview about those from the below link,
