apache/datafusion has 631,738 source lines of code out of 797,375 total lines across 2,072 files, counted from the 140c7c5a4cbde4409a4d29a4c04032d618c3b8ce ref at commit 140c7c5a4cbd by the OctoCounts tokei engine on 2026-09-16. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving apache/datafusion to commit 140c7c5a4cbd, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
