A Spark-based data comparison tool at scale which facilitates software development engineers to compare a plethora of pair combinations of possible data sources. Multiple execution modes in multiple environments enable the user to generate a diff report as a Java/Scala-friendly DataFrame or as a file for future use. Comes with out of the box SparkFactory and SparkCompare tools.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 8 stars here means stars gained during the window, not the repo's star count.
