Subject Re: Release Flink 1.0.0
Date Mon, 25 Jan 2016 14:36:04 GMT
I agree, with Gyula, one out-of-core state backend should be in. We are
pretty close to that. Aljoscha has done good work on extending test
coverage for state backends, so we should be pretty comfortable that it
works as well, once we integrate new state backends with the tests.

There is a bit of work do do around extending the interface of the
key/value state. I would like to start a separate thread on that today or
tomorrow...
