F3
Points and comments are a snapshot, not live.
F3 is a research data file format embedding Wasm decoders for future-proof compatibility.
F3 is a columnar storage format designed to replace Parquet and ORC, addressing layout inefficiencies via a FlatBuffer-defined structure. Its key innovation is embedding WebAssembly (Wasm) binaries in each file (kilobytes) to decode data, ensuring interoperability without native decoders. The project is a research prototype for a SIGMOD 2026 paper, not production-ready. Benchmarks compare against Parquet, ORC, Nimble, Lance, TSFile, Bullion, and BtrBlocks. Code is MIT-licensed and available on GitHub.
What commenters are saying
Commenters criticized the README for lacking a clear 'why' and concrete advantages over Parquet. Many found the embedded Wasm decoders interesting but flagged security risks, noting past exploits with font VMs and PDF JavaScript. Some saw the sandboxed Wasm approach as manageable. A split emerged: some argued the format addresses real Parquet shortcomings mentioned in the paper, while others dismissed it as a future research project with no adoption, citing zero commits in 8 months.
