Mark, I disagree. Setting common goals is a critical part of getting things done.
This doesn't commit the community to push out the release if the goals aren't met, but does mean that we will, as a community, seriously consider it. This is also an acknowledgement that this is the most important feature in the next release (whether major or minor) for many of us. This has been in limbo for a very long time, so I think it is important for the community to commit to getting it to a functional state. It sounds like your objection is to this commitment for 3.0, but remember that 3.0 is the next release so that we can remove deprecated APIs. It does not mean that we aren't adding new features in that release and aren't considering other goals. On Thu, Feb 28, 2019 at 10:12 AM Mark Hamstra <m...@clearstorydata.com> wrote: > Then I'm -1.
