In the context of b2b data enrichment tools, each update operation is associated with a version number or a timestamp. When a client or service wants to update a document, it first checks the version or timestamp to ensure it matches the version of the document it has. If they match, the update is allowed, and the version is incremented. If they don’t match, it indicates that another update has occurred in the meantime, and the client needs to reconcile the changes. This approach helps maintain data consistency and integrity when multiple users or services are interacting with the same document in a b2b data enrichment scenario.
