Revision as of 08:46, 8 March 2016

Meeting Time: Every Wednesday at 13:00 UTC in #openstack-storlets

Agenda:

• Prioritize patches (suggestion):
  • COPY fix
    • https://review.openstack.org/#/c/283486/ (COPY functionality)
  • Range fix
    • https://review.openstack.org/#/c/282931/ (Prohibit storlet execution with range header)
    • https://review.openstack.org/#/c/283423/ (Add X-Storlet-Range header to specify input range)
  • Refactoring
    • https://review.openstack.org/#/c/282135/ (Refactor unit tests about storlet docker gateway)
    • https://review.openstack.org/#/c/280570/ (already has +2/+A, but waiting 282135)
    • https://review.openstack.org/#/c/276545/ (Improve timeout handling) should be rebased after range patches get merged
    • https://review.openstack.org/#/c/282211/ (Use contextmanager to manager file descriptors)
  • Others
    • https://review.openstack.org/#/c/285947/ (Refactor directory structure about python modules): Should be fixed
      • We should decide when we rebase/merge this, to avoid many merge conflicts caused by it. [takashi]

• Storlet in Hackathon etherpad
  • I would like to add another analytics related question.
  • What timeframe do we think we need?

Austin:

• We currently have the following abstract
  • Title: From Analytic to Image Processing in Swift with Openstack Storlets
  • Openstack Stolets is an emerging Openstack project aimed at pushing down data centric compute jobs to the object store. Storlets offer a server-less programming model enabling developers to quickly develop and deploy data path computations without worrying about the underlying platform details.
  • Storlets facilitate several interesting use cases such as:
    • Performing image processing in the storage, allowing to process large objects without downloading it.
    • Spark analytic push down to the store, saving on both bandwidth and memory in the analytic cluster.
    • Data obfuscation and anonymization at the source. Thus, preventing sensitive data from ever leaving the store.
  • In this talk we will present the project, discuss and demonstrate the use cases and present a PoC about an effective architecture for image processing using Storlets done at NTT.

    • https://bugs.launchpad.net/storlets/+bug/1534455
  • patches
    • https://review.openstack.org/#/c/282931/
    • https://review.openstack.org/#/c/283423/
• FD leak
  • FD leak in Storlet GET: https://bugs.launchpad.net/storlets/+bug/1537982 (Fix Released)
    • https://review.openstack.org/#/c/272379/ ... merged
  • There are other possible FD leaks, which may happen in timeout/exception case.
    • Use context manager to make sure all FDs are closed: https://review.openstack.org/#/c/282211/ (patch should be fixed)
