Well, let me propose the following milestones for 2.1 release then. Code freeze: June 2nd. Final QA and benchmarking: June 5 - June 8 Voting: ~ June 9 Release: ~ June 13
Also I heard H2 has to be released once again to support Ignite’s CREATE table command. Think that we should talk to H2 folks to make it happen in June 22nd - June 2nd time frame. — Denis > On May 11, 2017, at 2:26 AM, Pavel Tupitsyn <ptupit...@apache.org> wrote: > > As for .NET, I would propose to concentrate on peer deployment (IGNITE-2492) > and related stuff, like IGNITE-1894 .NET: Delegate support in the API via > extension methods. > > SQL Dependency does not look important to me, we can reschedule it for > later versions. > > On Thu, May 11, 2017 at 12:01 PM, Dmitriy Setrakyan <dsetrak...@apache.org> > wrote: > >> Vyacheslav, I think it is worth the research, but you should always keep >> data querying and indexing in mind.
