Can someone explain the meaning of 'Automatic cleaning not available/needed for this backend' in memcache?

Help needed with memcache warning in PHP Zend\n\nI recently set up memcache in my PHP Zend project. Everything appears to be working fine, but I noticed an odd warning in the logs. It says:\n\n\nZend_Cache_Core::save() / automatic cleaning is not available/necessary with this backend.\n\n\nI’m not entirely sure what this warning implies or if it indicates a serious issue. Is this a standard message for memcache systems, and does it affect performance or functionality?\n\nSince I am relatively new to caching technologies, I would really appreciate any insights from others who may have encountered this before. What steps, if any, should I consider taking to resolve or address this warning?\n\nThanks in advance for the help and advice!

The warning you’re encountering is standard for memcache implementations. It simply indicates that memcache manages data expiration differently compared to other caching systems. Unlike some backends that require periodic cleanup, memcache handles this automatically through its built-in expiration mechanism.

This message doesn’t signify a problem with your setup or impact performance. Memcache is designed to be efficient and low-maintenance. As long as you’re setting appropriate expiration times for your cached items, the system will manage itself effectively.

If you’re concerned about optimal performance, focus on monitoring your hit rates and adjusting your caching strategy accordingly. The warning itself can be safely ignored in most cases.

yo SwimmingFish, no need to sweat it! that warning’s just memcache being memcache. it handles cleaning differently from other caches, so that message is kinda its way of sayin ‘i got this’. as long as ur cache is workin fine, ur golden. how’s the overall performance been?

hey there SwimmingFish! that warning is actually pretty normal for memcache. it’s just saying memcache doesnt need automatic cleaning like some other cache types. no worries about performance or functionality! have u noticed any actual issues with ur caching? curious to hear how its working for u overall!
