Fundamentals: What Is Zarr? A Cloud-Native Format for Tensor Data - Earthmover What Zarr is, and how it enables fast, scalable access to multidimensional array data in the cloud.

Our latest fundamentals blog post provides an overview of @zarr.dev and its open-source ecosystem. Read more: earthmover.io/blog/what-is...

1/ Our team just got back from an inspiring week at the @cloudnativegeo.org conference in Snowbird, Utah, and one thing is clear: 𝐙𝐚𝐫𝐫 𝐚𝐝𝐨𝐩𝐭𝐢𝐨𝐧 𝐢𝐬 𝐬𝐮𝐫𝐠𝐢𝐧𝐠 𝐚𝐜𝐫𝐨𝐬𝐬 𝐠𝐞𝐨𝐬𝐩𝐚𝐭𝐢𝐚𝐥.

📣 Our team is heading to the
@cloudnativegeo.org
Conference in Snowbird, Utah. We’ll be sharing our latest open-source work on Xarray, Zarr, VirtualiZarr, Icechunk, and leading a hands-on workshop, 𝑍𝑎𝑟𝑟, 𝐼𝑐𝑒𝑐ℎ𝑢𝑛𝑘, & 𝑋𝑎𝑟𝑟𝑎𝑦 𝑓𝑜𝑟 𝐶𝑙𝑜𝑢𝑑-𝑛𝑎𝑡𝑖𝑣𝑒 𝐺𝑒𝑜𝑠𝑝𝑎𝑡𝑖𝑎𝑙 𝐷𝑎𝑡𝑎-𝑐𝑢𝑏𝑒 𝐴𝑛𝑎𝑙𝑦𝑠𝑖𝑠.

The great @jacbeh.bsky.social interviewed me for the blog of the @egu.eu Ocean Sciences (OS) Division. It was fun to talk about my career path, research that has led to receiving the Fridtjof Nansen Medal, as well as challenges faced in academia

💡 Another banger technical blog post by @functionth.bsky.social! This one explains Icechunk's transaction system via the example of bank account transfers. Having true ACID transactions for the array data model is such a game changer!

With today's Zarr Python release, switch to the new obstore-based backend for **3x faster** reading from S3, Google Cloud Storage, and Azure than the default fsspec backend.

Zarr cartoon about how having to download all the data before looking at any of it is an antiquated paradigm.

Thank you @tegnicholas.bsky.social

Fundamentals: What is Cloud-Optimized Scientific Data? What cloud-optimized data really means, and how Zarr and Icechunk enable fast access to massive scientific datasets in cloud object storage.

1/ 💡 Our latest blog post in the fundamentals series, written by @tegnicholas.bsky.social, demystifies cloud-optimized scientific data formats!

Imagine if all you had to do to serve geopspatial data over OGC APIs was to ingest @zarr.dev datasets into cloud object storage...and the platform handled the rest. Scaling, logging, metrics, auth, etc. That's Flux! Join our webinar if you want to learn more.

I have to admit that I too was confused about how S3 prefixes and scalability work before reading this post by @functionth.bsky.social.

This one was a lot of fun to work on! Why @xarray.bsky.social and @zarr.dev are faster than DuckDB and Parquet for gridded data...from first principles.

I am so excited to share this new project with NASA and @developmentseed.org . By applying Icechunk and the "virtualization" approach, we can make Petabytes of archival data accessible to high performance analytics. Unlocking NASA's cloud archives will have immense downstream benefits for the world.

1/ As a data platform company, we get a unique view of how other companies use data. In light of the recent cuts at @noaa.gov, our CEO, @rabernat.bsky.social, reached out to our customers to get their perspective on the value of NOAA’s data and services.

24HOP Open Men Duo Podium

Here on Bluesky, I follow two topics: 1) software & data infrastructure and 2) cycling. I mostly post about software but today, I can share a bit about a fun cycling adventure of my own 🚵‍♂️.

Last week, I got to ride in the 24 Hours in the Old Pueblo - placing 4th in the Open Men Duo category:

We now have a public slack channel for VirtualiZarr development and questions, feel free to join!

Denver Geospatial Happy Hour · Luma Come have a drink, grab a bite, and nerd out with the Earthmover team on geospatial data. Earthmover will provide food and drink tickets. Our event will be…

Denver folks — join us for a Geospatial Happy Hour on Wednesday, March 12th at 7 PM MST. Come enjoy drinks, tacos, discussing geospatial data, and meeting the Earthmover team. Register: lu.ma/o6r39p6j

One reason we started @earthmover.io was to create a home for amazing open source devs building towards a shared vision for a cloud-native future. So I couldn't be more excited to have @tegnicholas.bsky.social joining the team! 🚀 Tom's capabilities as an engineer are unparalleled!!!

Have you ever waited a long time for @xarray.bsky.social to open up a large @zarr.dev dataset in cloud storage? Upgrade to Zarr 3 for a massive performance improvement! 🚀

Register for tomorrow’s webinar, Data Version Control for Arrays with Icechunk. bit.ly/3WVPSf2 @rabernat.bsky.social will discuss Icechunk’s application in AI/ML model development, how it adds safety + flexibility to data pipelines, & how it enables git-style version control to Zarr Arrays + Groups

Next week I'll be giving a webinar on one of my favorite parts of Icechunk--the ability to apply git-style version control to Zarr arrays and Groups. This capability makes data workflows so more safe, robust, and reproducible. Come check it out! (Registration link below.)

Join our webinar, Data Version Control for Arrays with #Icechunk. @rabernat.bsky.social will explain how Icechunk’s transactions, snapshots, tags, + branches can add safety & flexibility to data pipelines and workflows. Register here: bit.ly/3WVPSf2

This is a golden opportunity to educate the public about how basic research works in this country, and the benefits it brings across the board - including to businesses. How we became the most dynamic economy in the world through research investment...

Excited to be spending a couple of days out in SF! I always forget just how nice this city is (especially coming from NYC in February! 🥶)

NYC folks — @rabernat.bsky.social will be leading a technical workshop, Navigating Weather and Climate Data, on Tuesday as part of the #GeospatialRiskSummit. Ryan will teach attendees the current state-of-the-art technology for analyzing weather and climate data and share visions of the future.

Why do we need a cloud-native data lake for geospatial data?

@rabernat.bsky.social and I recently sat down with Ian and Tim from the Infra Pod to discuss...

This conference was extremely fun and stimulating. We had a ton of traffic at the @earthmoverhq.bsky.social booth. I’m 100% convinced that solving “boring” data infrastructure problems can help accelerate work across the weather and climate enterprise. Excited up about the opportunities ahead!
