apache/spark has 1,003,344 source lines of code out of 1,557,817 total lines across 6,004 files, counted from the a512bc310d511442e20260edb05d01caf825e8a5 ref at commit a512bc310d51 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/spark to commit a512bc310d51, 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.
