Sorry, but no, there is no logical redundancy in my approach. Every client
queries only the info they want to know. It is extremely rare when client
wants the whole database. Usually, client query filters most of the data out
according to some criteria. The other common case is aggregated report,
where the output is small as well. In both cases extra information is
quickly discarded on server and would never cross the network boundary.
Whereas in your broadcasting proposal you flood the network with spam that
clients rarely care about.
