The following diagram illustrates data flow implemented by the
Distributed Engine. Note that the rectangles -- shard1,shard2, shard3, client1
and client2, can be placed on the physical different hosts or on the same host,
or in any combination. For example shard1, shard2, client1 on one physical node
and shard3 and client2 on another physical node.
The Distributed SQL Engine sends a query to one of the network nodes,
or broadcasts queries to all nodes.
