Reladiff is a high-performance tool and library designed for diffing large datasets across databases. By executing the diff calculation within the database itself, Reladiff minimizes data transfer and achieves optimal performance.

Cross-Database Diff: Reladiff employs a divide-and-conquer algorithm, based on matching hashes, to efficiently identify modified segments and download only the necessary data for comparison. This approach ensures exceptional performance when differences are minimal.

🧠 Gracefully handles reduced precision (e.g., timestamp(9) -> timestamp(3)) by rounding according to the database specification.

Intra-Database Diff: When both tables reside in the same database, Reladiff compares them using a join operation, with additional optimizations for enhanced speed.
