How to exclude a cache table from memcache? I have created a one custom table for storing the data, based on cache rules i have created a table.

Installed and enabled Memcache module in site.

Configured memcache in settings.php 

  $conf['cache_backends'][] = 'sites/all/modules/memcache/memcache.inc';
  $conf['lock_inc'] = 'sites/all/modules/memcache/memcache-lock.inc';
  $conf['memcache_stampede_protection'] = TRUE;
  $conf['cache_default_class'] = 'MemCacheDrupal';

  // The 'cache_form' bin must be assigned to non-volatile storage.
  $conf['cache_class_cache_form'] = 'DrupalDatabaseCache';
  // Don't bootstrap the database when serving pages from the cache.
  $conf['page_cache_without_database'] = TRUE;
  $conf['page_cache_invoke_hooks'] = FALSE;
  $conf['cache_thrive_tips'] = 'DrupalDatabaseCache';
  $conf['memcache_servers'] = array('localhost:11212' =&gt; 'default');


When i configure memcache in my site, at that time onwards my custom table(cache_abc) not storing any values.

How can i exclude only this table from memcache?
You do it in the same way the  code you are showing does for cache_form.

$conf['cache_class_cache_abc'] = 'DrupalDatabaseCache';


Adding that line in the settings.php file, you are telling Drupal to save the cache for cache_abc in the database.

Keep in mind that, in Drupal cache terminology, cache_abc (which would be the name of the database table containing the cache data, when the cache is saved in the database) is called bin.
