Meet @rabernat.bsky.social, @jhamman.bsky.social and more of the Earthmover team at our #ClimateWeekNYC events. PSA: the hands-on tech workshop Wednesday and panel on Thursday still have capacity, but are filling up fast.

Super excited to see #icechunk v1.0 ship today. Stable format, stable API, and ready for production. Take it for a spin and let us know how it goes. 🚀🚀🚀

Just back from #CNG2025, I wrote up some thoughts on the traction the @zarr.dev format is gaining in the broader geospatial industry (specifically Earth Observation). I also summarize what features and tools the user and developer communities are asking for to fully leverage Zarr. 👇👇👇

I'll be at the CNG conference in Snowbird next week. I wrote a short blog post about what the Earthmover team will be up to. tldr; we'll be talking about @zarr.dev, #icechunk, @xarray.bsky.social and cloud-native data cubes. Details in the blog post 👇

Most people think of @zarr.dev as a "file format". With #Icechunk, we've turned Zarr into a database. @functionth.bsky.social's post shows how Icechunk can be used to solve a problem where transactional databases are often required.

There's still time to sign up for tomorrow's webinar on ⚡Flux ⚡ 👇 share.hsforms.com/1FLrE9CpwSLq...

@zarr.dev and #icechunk are amazing but they are not magic. They are part of a thoughtfully designed cloud-native data architecture. @tegnicholas.bsky.social peels back the covers on cloud-optimized scientific data formats in our latest "Fundamentals" post 👇

We found similar results when we first benchmarked #icechunk. Our conclusion: doing IO with a Rust backend is much faster than Python. 👇Really exciting to see @kylebarron.dev's Obstore backend for Zarr-Python ship today.

🚀 Big launch today: introducing Flux — a game-changing way to serve geospatial data via standard APIs in seconds. Built for scale, speed, and simplicity.

Training AI models at scale from data stored in cloud object storage requires thinking carefully about both bandwidth and concurrency. In this post, @functionth.bsky.social get’s into the details of concurrent reads at scale, showing how #Icechunk and S3 can easily scale beyond 200k requests/second!

📣 Blog post alert! 𝐄𝐱𝐩𝐥𝐨𝐫𝐢𝐧𝐠 𝐈𝐜𝐞𝐜𝐡𝐮𝐧𝐤 𝐬𝐜𝐚𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲: 𝐮𝐧𝐭𝐚𝐧𝐠𝐥𝐢𝐧𝐠 𝐒𝟑'𝐬 𝐩𝐫𝐞𝐟𝐢𝐱 𝐬𝐭𝐨𝐫𝐲. This technical post by @functionth.bsky.social dives deep into the internals of how S3 shards data, showing that distributed Icechunk can easily perform 230,000 object reads/sec and beyond. earthmover.io/blog/explori...

We often see folks try to convince tabular data tools to perform well with multi-dimensional array data. This post by @rabernat.bsky.social explains, from first principles, why this rarely works. Its a good one! 👇👇👇

Super exciting to see @copernicusecmwf.bsky.social starting to adopt @zarr.dev!

🚨 New blog post 🚨 In it, we show off our recent work deploying #icechunk on top of #NASA's existing archives of Earth observation data. The results: 100x speed up when extracting time series from existing datasets stored as netCDF.

This session is going to be a blast! If you are headed to CNG next month (and you should be!), consider joining us for this workshop on @xarray.bsky.social , @zarr.dev , and #icechunk. 👇👇👇

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.

I'll be giving a short update tomorrow on the state of Zarr-Python following the 3.0 release back in January. Swing by the Pangeo showcase to catch the latest progress. @zarr.dev

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

We now have a public slack channel for VirtualiZarr development and questions, feel free to join! earthmover-community.slack.com/archives/C08...

Very, very stoked to have @tegnicholas.bsky.social join the Earthmover team!

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:

Zarr-Python 3 included a bunch of performance improvements that are now landing in @xarray.bsky.social. Check out @davisvbennett.bsky.social's post on what we changed in Xarray/Zarr and how it is speeding up the "time to first byte" for large datasets 👇

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... creators.spotify.com/pod/show/yet...

If you missed the Zarr-Python 3 release party last week, no worries because today, we released zarr-python 3.0.1 and numcodecs 0.15.0. release notes 👉 zarr.readthedocs.io/en/stable/re...

Come to our booth at AMS where we'll be giving out demos of Arraylake and Icechunk as well as Rubik's cube lessons!

We’re thrilled to announce the release of @zarr.dev-Python 3! This major release brings full support for Zarr v3 specification, including the new chunk-sharding extension, major performance enhancements, and a thoroughly modernized codebase. Read more: earthmover.io/blog/zarr3-r...

Our friends over at @zarr.dev made a big release today. Xarray v2025.01.1 was also released today with support for Zarr-Python 3 🚀

🎉 Zarr-Python 3 is here! 🎉 - Full support for Zarr v3 spec - Chunk-sharding for more efficient data storage - Major performance boosts with async I/O & parallel compression 💻 pip install --upgrade zarr 💻 conda install --channel conda-forge zarr Blog post: https://buff.ly/3C3OwYw

We released Zarr-Python 3 today, complete with support for the v3 spec, new extensions (chunk-sharding) and significant performance gains. earthmover.io/blog/zarr3-r...

Are you headed to #AMS25 next week? We're hosting the @pangeo.io happy hour and would love to have you join us! lu.ma/ddtba5f5

Hi, Zarr community! 👋 🚨 Big news: Zarr-Python 3.0 is dropping next week! 🚨 If your project depends on Zarr-Python, make sure to check out the migration guide to get ready for the update. Guide: https://buff.ly/3W0cLxd More updates soon! 🧑🏻‍💻

I'm still recovering from #AGU24 but I'm already thinking ahead to #AMS25. Who's going to be in New Orleans and who wants to meet up?

At #AGU24 last week, I gave a talk titled "Seamless Arrays: A Full Stack, Cloud-Native Architecture for Fast, Scalable Data Access". Slides and some summary below 👇 doi.org/10.6084/m9.f...

Please help the #Zarr community welcome @normanrz.bsky.social as the newest member of the Steering Council! 👏🏼 zarr.dev/blog/steerin...

You’ll find me at our booth Tuesday, Wednesday and Thursday morning. Anyone need Rubik’s cube lessons? 🤓

@rabernat.bsky.social is rounding out the week of #AGU24 with his talk, “How can we make cloud computing actually accessible to all scientists?” on Friday at 5:10 PM agu.confex.com/agu/agu24/me...

On Thursday at 3:00 PM, @jhamman.bsky.social is presenting “Seamless Arrays: A Full Stack, Cloud-Native Architecture for Fast, Scalable Data Access” agu.confex.com/agu/agu24/me... #AGU24

Will you be at #AGU24 next week? Earthmover is exhibiting in booth 1007! @rabernat.bsky.social and @jhamman.bsky.social are participating in panel discussions and giving talks👇.

Getting excited for #AGU24 next week in DC! I'll be giving a talk on Friday evening 😱 called "How can we make cloud computing actually accessible to all scientists." If you can't stay till the bitter end, come find me at the @earthmoverhq.bsky.social booth (#1007)! agu.confex.com/agu/agu24/me...

I'll be heading to #AGU24 next week and I'm looking forward to seeing folks there. Here's a quick thread on what I'll be up to. 🧵

I'm finally making the jump over from the other site. I hear this is where the action is at! Stay tuned for posts on open source software (@zarr.dev and @xarray.bsky.social), data (à la @pangeo.bsky.social), the cool stuff we're working on at @earthmoverhq.bsky.social, climate science, and bikes.
