Dask Heartbeat by Coiled: 2021-03-04

The Dask community is highly distributed with different teams working independently. This is powerful but sometimes makes it hard for people within the community to see everything that is going on. The Dask Heartbeat by Coiled is a monthly publication intended to centralize and broadcast Dask news over the previous four weeks.  

If you want something added to this list either send an e-mail at info@coiled.io, or tweet and tag @dask_dev and we’ll try to include it. Keep reading for the latest updates.

Dask Distributed Summit 

The Dask community is hosting a remote conference from May 19-21st! Details about how to attend and/or present are available at https://summit.dask.org. Matt Rocklin (Coiled) also wrote up some thoughts on Dask conferences in general. 


Both Dask and Distributed version 2021.02.0 were released on February 5, 2021.

Dask monthly community meeting 

The March Dask community meeting was quite active. Some highlights from the meeting are:

  • Ben Zaitlen (NVIDIA) and Julia Signell (Saturn Cloud) were added as new Dask GitHub organization owners (thanks to both of them for all their hard work).
  • Tom Augspurger (Microsoft) demoed a new library, stac-vrt, for efficiently building a GDAL VRT from a STAC collection (a mosaic of a bunch of images).
  • Simon Perkins (South African Radio Astronomy Observatory) demonstrated how he and his team have been using Dask’s new annotation machinery to increase the performance of large array workloads by reducing dependency transfers between workers. We look forward to Simon’s blog post on this topic.
  • The Dask GitHub organization will start experimenting with Orbit to track community engagement.
  • The Dask community is thinking about hiring a community manager. This would be a semi-technical role to track the issue tracker, curate other systems like Slack/Discourse, engage with developers, organize blog posts, and more.
