A high-performance, zero-overhead, extensible Python compiler using LLVM.

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.

"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.

A high-performance, zero-overhead, extensible Python compiler using LLVM.

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.

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.
