memcached is a fully featured Memcached client for Node.js. but i seem plugin for meteor . i couldn’t found . what is the reson of that redis have best perform on meteor + mongo rather than memcache.
The reason why Redis works better than Memcached with Meteor is because Redis has a Keyspace Notification Event mechanism, which allows support for Pub/Sub.
Changes to Memcached data can only be detected by polling.
