🚨 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!

Blosc2 + Caterva2 + Numba = ⚡⚡

We're making HDF5, the standard for scientific data 📊, faster ⚡ and more versatile 🛠️. By integrating Blosc2 with HDF5, our Caterva2 platform allows you to natively serve ☁️, share 🤝, visualize 👀, and compute 💻 your HDF5 datasets with greater efficiency and ease.

Welcome to the team, Luke!

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.

Did you know Caterva2 has native support for HDF5 files 📂 ? Here at ironArray we are constantly working 🛠️ on the software to offer an improved product to our users - checkout how to use the unfold 📖 command to expose your .h5 files to Caterva2's powerful analysis toolkit 🧰 - > ironarray.io/caterva2

📣 #Caterva2 2025.8.7 is out! 🚀

We did a major refactoring for a simpler, more robust system, with client APIs unaffected. ✅

The highlight is the new cat2agent 🤖, a CLI client to watch a directory and auto-sync it with a Caterva2 server.

#OpenSource

In this chapter, our Luke Shaw explains how filters work in Caterva2, a free software that you can run on your own laptop (or server, if you are more serious about large datasets). It works for either #Blosc2 or #HDF5 datasets.

Have it a try!

📣 Video demonstrating the demo originally planned for the HDF5 HUG event at DESY, Hamburg. Thanks to the HDFGroup for the opportunity to present our work on
Blosc2, Caterva2 and HDF5. Happy to contribute to the HDF5 ecosystem!

Enjoy!

#HDF5 #Tomography #DataVisualization #Python #Cat2Cloud

Thanks to the advanced double partitioning techniques in #Blosc2, our #Caterva2 package can serve small slices of big datasets (3.8 GB) through internet in less than the blink of an eye.

📢 Caterva2 2026.9.2 is out! 🚀

Intelligent compute & caching for Blosc2 & HDF5 repositories.

Highlights:
✅ C2Cache peer caching
✅ Blosc2 CTable (.b2z) support
✅ Virtual roots (.b2z/.h5)
✅ Concurrent chunk writes
✅ Embedded JupyterLite

Share Faster, Compute Bigger 🚀

📢 Python-Blosc2 4.12.0 is out!

Remote arrays work over S3/GCS/HTTP via fsspec. lazy=True fetches only the blocks needed and reuses a validated cache — 5–17x faster in S3 benchmarks.

Also: concurrent Caterva2 writers + UTF-8 indexes.
