Open source data-diff

Datafold announced the discontinuation of active support for its open-source tool, data-diff, as of May 17, 2024, but offers a free trial of Datafold Cloud for ongoing in-database and cross-database diffing needs. Data-diff was launched as an open-source solution designed to automate data quality checks during data replication and migration, addressing common issues such as message loss and inconsistencies due to hard deletes or stale update timestamps. Traditional methods of validating data consistency across databases, such as comparing row counts or hashing, are either too crude or inefficient; data-diff offers a more effective solution by using a binary search-like algorithm on hashes, which enhances both speed and accuracy by only transferring hash values over the network. This method is both IO efficient and highly parallelizable, allowing users to efficiently compare large datasets across different databases. Despite the tool's discontinuation in active development, it remains a significant contribution to addressing data replication challenges faced by many data teams.
