InMemory is an awesome concept and I have been fortunate to learn about the same from my friends in the industry over blogs. It holds deep concepts and is sometimes tough to understand how the building blocks come together. I am not the only one doing the exploration, but a number of you also do and pass those learnings to me via your interesting questions. Thanks to each one of you who take a moment to ask me some of these questions that shake the fundamentals and make my understanding stronger. In the same lines, one of the readers wrote back to me after reading the MSDN on InMemory OLTP, what does the concepts of Optimistic multi-version concurrency really mean. On first thought, it looks simple, but the question was very loaded.
