# DataX vs pathway

DataX and pathway share 4 technologies: MySQL, MongoDB, Postgres, and SQLite. DataX is written in Java and pathway in Rust.

- [alibaba/DataX](https://seerepo.com/r/alibaba/DataX): DataX是阿里云DataWorks数据集成的开源版本。
- [pathwaycom/pathway](https://seerepo.com/r/pathwaycom/pathway): Python ETL framework for stream processing, real-time analytics, LLM pipelines, and RAG.

| Who writes it | 0% of its commits signed by AI | 0% of its commits signed by AI |
| Activity | Last push July 7, 2026, 479 commits, 17,381 stars | Last push November 5, 2026, 2,335 commits, 62,021 stars |
| Tests | 36 test files. 5.1% of its code files have a test that imports them | 272 test files. 16% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
