Introduction
Recently I've read another article from the series: "we are better than a two-phase commit". Here I will not analyze the contents of this article (although I'm thinking about giving a detailed analysis). The task of my opus is to offer the most effective version of the distributed commit in terms of number of round trips. Of course, such a commit comes at a price. However, the goal is to assess and show that the two-phase commit is not a drag, as many believe.
It should also be noted that there will be no full-scale experiments and fake comparisons. Algorithms and theoretical analysis will be given simply. If desired, you can independently implement and test it in practice. Of course, it would be much better that this was presented in the current article, but it all depends on free time and motivation. In my opinion, it's more important to describe algorithms than to present charts, because almost everyone can draw the charts based on algorithms while the opposite is not true.
