What is Datafold’s resource consumption footprint? How will Datafold affect my data warehouse costs?
Recognizing the importance of efficient data reconciliation, we provide a number of strategies to make the diffing process as efficient as possible:Efficient AlgorithmThe diffing algorithm itself leverages stochastic checksumming which is optimized for efficiency at scale. It provides detailed comparison by pushing down the compute to both source and target databases without requiring the extraction of datasets for comparison.Flexible ControlsUsers can easily control the volume of data used in diffing by using:
Filters: Focus on the most relevant part of the dataset
Sampling: Set sampling as a percentage of rows or desired confidence level
Slim Diff: Selectively diff only the models that have dbt code changes in your pull request.
Workload ManagementUsers can apply controls to enforce low diffing footprint:
On the Datafold side: Set desired concurrency
On the database side: Most databases support workload management settings to ensure that Datafold does not consume more than X% CPU or Y% RAM
Also, consider that using a data quality tool like Datafold to catch issues before production will reduce cost over time as it lowers the need for expensive reprocessing and troubleshooting. Datafold’s features like filtering, sampling, and Slim Diff ensure that only relevant datasets are tested, minimizing the computational load on your data warehouse. This targeted approach can lead to more efficient resource usage and potentially lower data warehouse operation costs.
