Subject Re: Release Flink 1.0.0
Date Mon, 25 Jan 2016 15:29:02 GMT
Hi,
I think the refactoring of Partitioned State and the WindowOperator on state work is almost
ready. I also have the RocksDB state backend working. I’m running some tests now on the
cluster and should be able to open a PR tomorrow.
