@epahomov This PR may do everything that you want in terms of a streaming
iterator, but I can tell you with certainty that only being able to fetch a
single partition at a time does not meet every Spark user's needs. What this
PR can do is a strict subset of the functionality of
https://github.com/apache/incubator-spark/pull/421, and in the end I'm
persuaded by a more elegant implementation if and only if it meets an
equivalent set of user needs.
