Hi Emmanouil, The master branch has been initialized. I have raised a PR to migrate Flink module to ignite-extensions.
PR https://github.com/apache/ignite-extensions/pull/1 Jira : https://issues.apache.org/jira/browse/IGNITE-12356 Regards, Saikat On Sun, Nov 10, 2019 at 3:39 PM Emmanouil Gkatziouras <gkatzio...@gmail.com> wrote: > Hi all! > > This is an update.
