Hi, Great job, Gordon! Thanks a lot for driving this and wrapping features up to a detailed list. +1 on it!
Would be great if we can also add flip29 to the list. @jincheng sun <sunjincheng...@gmail.com> and I are focusing on it these days. I think these features in flip29 would bring big enhancements to the Table API. :-) Best, Hequn On Sun, May 5, 2019 at 10:41 PM Becket Qin <becket....@gmail.com> wrote: > Thanks for driving this release, Gordon. +1 on the feature list. > > This is a pretty exciting and ambitious release! > > Cheers, > > Jiangjie (Becket) Qin > > On Sun, May 5, 2019 at 4:28 PM jincheng sun <sunjincheng...@gmail.com> > wrote: > > > Thanks a lot for being our release manager, Great job! > > > > +1 for the feature list and It's better to add FLIP-29 > > < > https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=97552739 > > >(Support > > map/flatMap/aggregate/flatAggregate on TableAPI), as the goals of release > > 1.9. > > > > What do you think? > > > > Best, > > Jincheng > > > > Bowen Li <bowenl...@gmail.com> 于2019年5月5日周日 上午12:47写道： > > > > > +1, exciting and ambitious goals, the rough timeline looks reasonable. > > > Let's make it happen! > > > > > > On Sat, May 4, 2019 at 2:47 AM Jark Wu <imj...@gmail.com> wrote: > > > > > > > +1 for the 1.9.0 feature list.
