Here Facebook friend functionality would be a graph data structure.

We could have HashMap or key value store of (UserId,List of friends). This key value store can be partitioned based on names of the user or based on user location so that they could loaded in different servers.
Friend object can contain all the details of his friends and his posts.
For caching, we could cache just the accessed friend objects for a particular user in our local cache.

I think we can cache user and friends objects, but we should not cache notifications list.
