219 E2 files across 64 GitHub repositories. E2 is the AMP-engine variant of YXDB, produced by Alteryx's newer multi-threaded processing engine.
All source repositories have been submitted to the Software Heritage Foundation for permanent archival.
We searched GitHub for .yxdb\ files and found that most were produced by the classic Alteryx engine (E1), but a small number were produced by the newer AMP engine (E2). The two formats are distinct and not interchangeable.
