Add Semaphore, Condition, Event

Open mrocklin opened this issue 7 years ago • 7 comments

Dask currently has some distributed coordination primitives like Locks and Queues that match the API of normal local Locks and Queues. There are other primitives like these that we do not yet support, notable Semaphore, Condition, and Event.

These might be good training for people who want to become familiar with extending the dask.distributed system. The files lock.py, queues.py, and variable.py might be a good model for development here.

Hi, I've been writing python for some time but I'm new to distributed computing. This seems like the right issue to get started. Can I work on this?

Yes! Anyone can work on any issue. You may want to familiarize yourself with http://distributed.readthedocs.io/en/latest/develop.html

  • It appears that https://github.com/dask/distributed/pull/2690 is/was meant to implement one (Semaphore) of the missing features listed here. Are there any updates on the status of https://github.com/dask/distributed/pull/2690?

  • https://github.com/dask/distributed/pull/3397 mentions Events and Conditions. Is it the case that these two features have also been implemented already?

I am interested in working on the other features namely (Event, Condition), and wanted to make sure that I am not duplicating work that has already been done.

All communication is happening on github. I recommend checking in on that PR.

This is different. Dask uses Tornado/asyncio objects within its codebase. We would also like to expose distributed versions of these objects to users so that they can make their own applications.

👍 will do

Thank you for the clarification!

Can i work on the Condition part, it seems like Event has been implemented.
