>From a user model perspective, we should have a "load more" capability so that users can add data into an existing dataset using load-like DDL.  Under the hood this can essentially be an insert-into-from-external-files feature, i.e., it doesn't have to be optimized yet, beyond being executed as a single Hyracks job that does a series of inserts (into the dataset and its associated indexes) - as from a user's perspective today it is REALLY a pain to not be able to add more data after an initial load!  As a result we see folks having to do work around like loading into some other dataset and then doing an insert-into, or abusing feeds, or....  Let's fix this!  It can't be super-hard, as it would essentially operate like a short-lived datafeed under the hood.
