Spark Change Evidence Gate
A CI/CD add-on that automatically generates PR-ready evidence bundles for Spark/ETL changes: row-level diffs over a configurable lookback window, performance benchmarks, and runtime/partitioning diagnostics. It posts a standardized “promotion checklist” to GitHub/GitLab/Bitbucket and can enforce merge gates (or create auto-approvals) when evidence thresholds are met.

Spark Change Evidence Gate
A CI/CD add-on that automatically generates PR-ready evidence bundles for Spark/ETL changes: row-level diffs over a configurable lookback window, performance benchmarks, and runtime/partitioning diagnostics. It posts a standardized “promotion checklist” to GitHub/GitLab/Bitbucket and can enforce merge gates (or create auto-approvals) when evidence thresholds are met.
Target customer
Data Engineering managers and platform engineers running Spark pipelines on Databricks/EMR/Synapse who need faster, safer promotion of ETL changes without weeks of review friction.
Problem-solution fit
Teams are stuck in meetings and slow approvals because reviewers lack consistent, trusted evidence of correctness and performance impact. This product turns correctness validation (row-level comparisons) and performance regressions (runtime/parallelism metrics) into automated, repeatable artifacts that unblock approvals and reduce time-to-production while preventing accidental slowdowns.
