> *Problem*
> Ignite can work in two modes - server (default) and client. Both modes provide transparent cache API. 
> IGFS heavily rely on cache operations and sometimes perform lots of them with assumption that metadata is located on the same node, so these operations are cheap and do not require any cross-node communication. 
> But when user works with IGFS from client node, this code could be very inefficient because even single operation could cause many network round trips between a client and a server.
> *Solution*
> Provide special implementations of IGFS operations which will delegate the whole execution to the server, thus leaving only a single network round trip.
