"The LLVM of columnar file formats". A toolkit for working with compressed Arrow on-disk, in-memory, and over-the-wire.
Vortex is a toolkit for working with compressed Apache Arrow arrays in-memory, on-disk, and over-the-wire.
Vortex is designed to be to columnar file formats what Apache DataFusion is to query engines (or, analogously, what LLVM + Clang are to compilers): a highly extensible & extremely fast framework for building a modern columnar file format, with a state-of-the-art, "batteries included" reference implementation.
The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
Despite its name, LLVM has little to do with traditional virtual machines. The name "LLVM" itself is not an acronym; it is the full name of the project.

Pyston is an open source Python implementation that aims to be both highly compatible and high-performance. It uses modern JIT techniques on top of LLVM, and natively supports many CPython C extension modules via a recompile.

Codon is a high-performance Python compiler that compiles Python code to native machine code without any runtime overhead. Typical speedups over Python are on the order of 100x or more, on a single thread. Codon supports native multithreading which can lead to speedups many times higher still.

Codon is a high-performance Python compiler that compiles Python code to native machine code without any runtime overhead. Typical speedups over Python are on the order of 10-100x or more, on a single thread. Codon's performance is typically on par with (and sometimes better than) that of C/C++. Unlike Python, Codon supports native multithreading, which can lead to speedups many times higher still. Codon grew out of the Seq project.
