Can you please explain in detail, why you think so? There is no commit message explaining what each patch does so it is difficult to understand why you said so? Also, can you let us know if this supports 2PC in some way and if so how is it different from what the other thread on the same topic [1] is trying to achieve? Also, I would like to know if the patch related to CSN based snapshot [2] is a precursor for this, if not, then is it any way related to this patch because I see the latest reply on that thread [2] which says it is an infrastructure of sharding feature but I don't understand completely whether these patches are related? Basically, there seem to be three threads, first, this one and then [1] and [2] which seems to be doing the work for sharding feature but there is no clear explanation anywhere if these are anyway related or whether combining all these three we are aiming for a solution for atomic commit and atomic visibility. I am not sure if you know answers to all these questions so I added the people who seem to be working on the other two patches. I am also afraid that if there is any duplicate or conflicting work going on in these threads so we should try to find that as well.
