Hi Jonathan, I haven’t heard about it before, but now I’ve read it and it indeed offers something interesting. I’ve read blog post, paper and comments at Jira so I need to digest it a bit and let it sink in. Thanks for letting me know about it.
Can you tell me something more about the status of that feature? Would you like to have it? From what I see, discussion stopped year ago and it has minor priority so it doesn’t seem like a hot subject that everyone awaits. Maybe I can incorporate that as a building block for something more functional. While reading I noticed that some concepts resemble what I’ve been thinking about, but here it is obviously much more detailed and specified. I need to digest it. > On 07 Aug 2015, at 18:05, Jonathan Ellis <jbel...@gmail.com> wrote: > > Have you seen RAMP transactions? > > I think that's a much better fit for C* than fully linearizable operations > cross-partition. > > https://issues.apache.org/jira/browse/CASSANDRA-7056 > > On Fri, Aug 7, 2015 at 7:56 AM, Marek Lewandowski < > marekmlewandow...@gmail.com> wrote: > >> actually I have been also thinking about doing something like redundant >> execution of transaction.
