At AGU I talked to NASA people about how agencies could better support open-source tools they rely on. I argued that our recent collaboration between Xarray and NASA ESDIS on xarray.DataTree was a good model to copy - read about how it happened here! xarray.dev/blog/datatree

It was great to spend time with these amazing people, collaborating on building hierarchical structures in Xarray.

@alekpetty I'm hoping that virtual zarr datasets will make it easier to cloud-optimize data that was dumped in a bucket in a legacy format, and allow creating aggregated datasets with relevant derived information alongside it. github.com/zarr-developer…

@TEGNicholasCode yeah definitely. And yes data is migrating to the cloud (NSIDC is my main DAAC I'm involved with, and they are moving everything over through NASA mandates). Trying to do the same for our more derived datasets too but a little unclear on best strategies/repositories for that.

Completely agree - "in theory" we have the simple scalability of the cloud, but in practice it's often a headache, for no good reason, which prevents adoption by most users (including many scientists)

New Post: Cloud Computing is Broken matthewrocklin.com/cloud-is-broke… Investor asks: "What's next for Data/Cloud Infrastructure?" My answer: "Boring stuff. People struggle with basics." Cloud feels like MP3 players before iPod. In theory everything is good. In practice adoption is low

@alekpetty Makes total sense. On (1) and (2) some intermediate services (e.g. Coiled, Modal) would like to sell you the solution to this, but it's annoying that NASA + AWS can't just get it right first time On (3) - is your data in the cloud at least? If not in cloud-optimized format?

@TEGNicholasCode yes, e.g., 1) NASA isn't reliably providing us with cloud compute beyond some hubs, 2) AWS is a lot, hard for us to learn the fast-changing ecosystem in the limited time we have, 3) lots of our data not cloud optimized anyway so why bother

@mouthofmorrison @rabernat @betolink @EarthmoverHQ @steadyflux That said, it isn't 100% clear that NASA's best move is to immediately convert 10000+ data sets into cutting edge ARCO formats. Kerchunk and Virtual Zarr offer benefits of ARCO while keeping data in the native formats.

@mouthofmorrison @rabernat @EarthmoverHQ Tricky question, NASA has a mandate to keep it in archival, self describing formats... data would need to be duplicated and data conversion in most cases is not trivial. So At least 2x storing costs plus the overhead of data conversion.

We've talked a lot about #Icechunk's performance this week 🚀. But the Zarr-Python 3 results are also very encouraging! We're a few weeks away from the 3.0 launch but what this chart shows is that the new AsyncIO + multi-threading functionality in Zarr is going to be really good.
Tom Nicholas@TEGNicholasCode

ALSO this release is the first to be compatible with the much anticipated v3 implementation of zarr-python! (still on its beta branch right now) This brings big performance benefits when reading @zarr_dev on S3 via async and (b) compatibility with @EarthmoverHQ 's Icechunk.

All these integrations represent literally years-worth of effort, all coming out at once 🤯 And that's not even mentioning all the other changes you see in a typical xarray release!
