Using memcached/redis/alternative for small multiplayer game to update positions of objects

So I am making a small multiplayer game and I am using php as the backend. I basically need to SET and GET a lot of positions of objects, well one object is one player that has a X/Y position in this case.

I don't need todo it in realtime, but perhaps every 5-20 seconds since it's turn based. I don't mind if I loose data since positions will be set again by the clients every now and then.

I was thinking of doing this with memcached, or redis. Basically each player would开发者_Python百科 be a "key" and this key would contain an object with some relevant information, but the most important thing beeing the X/Y positions.

Perhaps I am going about this the wrong way but, this approach would seem very easy to do, however I am not sure how well it would work since I don't have a lot of experience with either of these soutions.

I should add that we are talking about perhaps 10 players here, hence 10 objects with x/y positions that needs updating every now and then.

Can it be done like this, is there a better solution than memcached/redis? If not which of these two would be better performance-wise? From what I understand it's almost the same thing, just that redis offers some more functionality (Which may not necessarily be needed).

Oh and yes I am also using APC with php obviously. Thanks!

With just 10 objects in the entire data model, I would store them all as a serialized array under a single key. The serialization time will pale in comparison to the memcached call, so you may as well minimize the number of reads and writes to one.

I just checked out the redis online demo, and it looks pretty neat. Thanks for the link. I can't speak to which is better, but memcached in PHP is proven and mature so you can't go wrong there.

Redis is cheapest on resources, especially 32 bit version, e.g. if you use less 2 GB cache memory, which is the case I believe, run 23 bit Redis even if your server is 64 bit.
