So, now you’re wondering. This Redis, is sounds very similar to Memcached, how do they compare? Well, let’s see. Memcached is indeed older than Redis, just as I suspected. However, Redis has accumulated many more features in a shorter amount of time, has a larger community, more documentation, and is otherwise simply better for newer projects than Memcached. Memcached is still useful if you have a project already using it, but otherwise it’s not recommended for much else.
