Not that I'm familiar with the PHP client, but if it's the same as in most others, then you can put whatever you want in there, and all gets and sets that have the same $server_key are guaranteed to end up on the same server every time. Exactly which server is not something you need to know.
The purpose of this function is to consolidate items that you often multi-get onto the same server, so that when you get them, you can do it in one operation hitting only one server. For example, say that you have three different user objects for a single user. When you set them individually, you use their user id as $server_key, and when you want to get all three objects, you simply do a getMultiByKey with the user id as $server_key. /Henrik Schröder On Fri, Oct 30, 2009 at 05:36, nard <[email protected]> wrote: > > Hello.
