PyArrow 21 was a great release, especially for @hf.co users: PyArrow now seamlessly handles hf:// URIs and does content-defined chunking to reduce transfer and storage costs on HF. Check out this blog post: huggingface.co/blog/parquet... #apachearrow #apacheparquet
Parquet Content-Defined Chunking
We’re on a journey to advance and democratize artificial intelligence through open source and open science.

Lots of improvements, medium and small, in this new release of the Apache Arrow monorepo (C++, Python, R, Ruby...). It also includes performance improvements in the Parquet reader that we contributed at @quantstack.bsky.social, and we hope to contribute more of them in the future.

The pycrdt Python library found its new home in the y-crdt organization.
Originally created for the Jupyter project, it is a general Yjs-compatible CRDT implementation that can be used in any project, independently of Jupyter.
