TODO

  • zeromq-memory-queue:
    • should store last ACK-ed at
    • should expose a method to get at its stats
      • read/s
      • write/s
      • transactions/s
      • queue lengths
      • memory used
      • last ACK received time
  • selectively tweak a queue (remove or edit items with a specified lkey from a queue)
  • write tests that checks for contention cases, when we have a lot of queues, queue items and workers.
  • flesh out the tests more for every edge case.
  • write implementation tests and split tests into behavior and implementation.

CHANGES

20120224 (vishnu@mobme.in)

  • TrueQueue

20111203 (vishnu@mobme.in)

  • Renaming redis_queue to queue

20111201 (vishnu@mobme.in)

  • A persistence server for the zeromq queue based on redis
    • The persistence server requests backlogs from the memory queue and stores updates in Redis
    • The persistence server sents an ACK for a backlog which says Redis processing has been successful.
  • The memory queue maintains a backlog of updates for which it hasn't received an ACK.

20111130 (vishnu@mobme.in)

  • An experimental zeromq backend and queue server.

20111128 (vishnu@mobme.in)

  • Modularizing the code so that we can now use multiple backends.
  • A memory based queue backend based on a C red-black tree implementation.
  • BREAKING. Queues are now created using: MobME::Infrastructure::RedisQueue.queue(backend) where backend is either one of :memory or :redis now.

20111118 (vishnu@mobme.in)

  • Store values inside small key-ed hashes for maximum memory efficiency.
  • Major reorganization, making everything far more modular & simple.

20111113 (vishnu@mobme.in)

  • Initial documentation in Yardoc style.
  • Adding #delete_queue(s) to clear & delete any and all queues permanently
  • Adding #peek to peek at the first element in a queue without deleting it.
  • #remove is now multi thread and evented systems friendly.
  • #remove can now take a block that will auto add the item back into the queue when an error happens or a {MobME::Infrastructure::RedisQueueRemoveAbort} is raised.
  • #list to list every element in the queue. This is an expensive operation.
  • Renaming #clear to #empty
  • Renaming #delete_queue(s) to #remove_queue(s)
  • More comprehensive documentation in README.md and TODO.md
  • Using Yajl instead of native JSON
  • Gemifying

20111111 (vishnu@mobme.in)

  • Organized the project into the formal MobME ruby tdd template
  • Wrote initial specs for everything implemented.
