2PC ?

• mratsim 6y ago
  2-Phase-Commit protocol i.e. a scheme with "prepare-commit" and eventual rollback.

    It is worth noticing that this paper presents a slightly more advanced protocol than 2PC. Relevant quote (page 21): > The major difference is that, in our scheme, the uncommitted state of the token prevents other atomic actions from reading it. The base 2PC protocol seems to be quite older than 1983. Arguably the first mention of 2PC in the literature is in "Notes on Data Base Operating Systems" by J. Gray (1978), and even that paper is "a compendium of data base management operating systems folklore".

    Yes I know what it is lol. I was asking if the paper just introduces that.
