At @quantstack.bsky.social we designed novel bit-unpacking SIMD optimizations for @arrow.apache.org and #ApacheParquet, and implemented them entirely using C++ metaprogramming instead of Python-based code generation. We'll publish a deep dive blog post soon. github.com/apache/arrow...

Arrow 23.0.0 was released on the 18th of January, check out some of the Release highlights on our announcement blog post: arrow.apache.org/blog/2026/01...
