Hi everyone, Thanks for your input. I've checked the MapR implementation and it has no annotation at all. Given the circumstances that we thought that MapR was already dropped, I would propose to immediately remove MapR in Flink 1.15 instead of first marking it as deprecated and removing it in Flink 1.16.
Please let me know what you think. Best regards, Martijn On Thu, 9 Dec 2021 at 17:27, David Morávek <d...@apache.org> wrote: > +1, agreed with Seth's reasoning.
