Retrieve Rows for specified keys in order

[al...@ceid.upatras.gr]

I am trying to retrieve the Row objects for a List of keys, in
StorageProxy. I accomplish this in two phases: at first I make a List of
ReadCommands, one for each key, and then I give this list to
readProtocol().

My problem is that the List returned by readProtocol() has many Rows in
different indices than the List of ReadCommands, and so I cannot directly
associate the results with the keys.

I had previously done this by retrieving the Rows one by one (one call to
ReadProtocol for each key), but that was too slow and I am trying to avoid
it. I could loop through the results and match the keys, but that would
also be too slow.

Is there any way to guarantee that readProtocol()'s results will
correspond to its input?
