> Currently, when we replicate a REST API call to all nodes in the cluster, we 
> wait until we get back a Response object for each node. We then go to the 
> Response Mapper and merge those responses into 1 NodeResponse. This merging 
> is done serially, and this is where we actually do the reading of the 
> response. We need to instead do this merging in parallel or buffer responses 
> in parallel and then merge then when done.
