🚨 Double threat!: Blosc2 3.12.2 + Caterva2 2025.12.3 release!🚨

✅ Streamlined computation for LazyUDFs
✅ Upload LazyUDFs for server-side execution in Caterva2

And as another consequence, Numba can now be integrated into your Blosc2 LazyUDF workflow very easily!

🤔 Can a library that computes on compressed data actually outperform performance heavyweights like NumPy and NumExpr?

During the walk, I'm also introducing a funny anecdote back when NumPy was a 👶

Enjoy!

🗣️ Announcing Python-Blosc2 3.8.0 🚀

A step closer to compliance with the array-api standard: data-apis.org/array-api!
This is an effort across all array-based libraries so that your code works (e.g. for both blosc2 and NumPy) by simply changing the import statement below!

Hats off to the excellent work that @lshaw-ironarray.bsky.social is doing to the @ironarray.io and @blosc.org ecosystems.

Fancy indexing is like a wild animal difficult to tame, but in this particular case he did an outstanding work at it! 👏
🗣️ Announcing Python-Blosc2 3.6.1

¡Unlock new levels of data manipulation with #Blosc2! 🚀
We've tamed the complexity of fancy indexing to make it intuitive, efficient, and consistent with NumPy's behavior.

📢 Blosc2 just launched a super-efficient array concatenation feature! 🎉

Combine massive arrays quickly and with minimal memory. If your array chunks are aligned, it's even faster! Perfect for big data tasks.

Caterva2 also supports filtering 🗃️data with fields, via the web client 🌐 or programmatically from Python code 🐍- even the most advanced queries are possible!
This makes it ideal for structured datasets for Data Science 🧪. See 👀 what Caterva2 can do !-> ironarray.io/caterva2.

We connect the Single Source of Truth (SSoT) concept to lazy expressions and Cat2Cloud's powerful append.
We also see how to seamlessly switch between notebooks and the web client.
