In this release, we’ve made it even easier for you to get started. New features allow the SDV to auto-detect important elements from you real data when creating your metadata file.
Detect primary and foreign keys. With the new updates, the SDV looks for primary keys in your tables, as well as potential foreign keys that may connect two tables. This will help you discover the overall structure of your schema.
Detect datetime formats. The SDV can now infer datetime values from you columns and determine the format string.
Discover categorical columns. Do you have discrete categories that are encoded using numbers? The SDV will detect these columns to improve your synthetic data quality.
Calling attention to unknown columns. The metadata detection is not perfect. The SDV will call out unknown columns for you to verify. By default, we’ll treat unknown columns as PII, ensuring that you do not accidentally leak any PII information.
An accurate metadata file is the key to high quality synthetic data. To see these features in action, check out the Metadata Creation Demo .
Additional Updates
- Enterprise users can anonymize their metadata to obfuscate column and table names. This makes it easier to share your metadata if this information is sensitive.
- You can now visualize the cardinality of a parent-child relationship. This allows you to see if the synthetic data is correctly capturing the # of children that each parent rows has.
