This paper discusses distributed transactions, addressing the problem of providing ACID-style semantics in a shared nothing environment.
As you read the paper, consider the following questions:
- How does the two phase commit (2PC) protocol work? What problem does it solve? What are the costs of using it?
- What is the significance of the Presumed Abort/Presumed Commit variants of 2PC? How do they reduce the overhead of 2PC? When should you choose one over the other?
