- 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.
Swift Hackathon
- See the following etherpad
Bugs
- Range handling: on going
- 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)
- FD leak in Storlet GET: https://bugs.launchpad.net/storlets/+bug/1537982 (Fix Released)
