An online concierge system receives, from a client device associated with a user, a request to access a user interface including a listing of sources associated with the system, in which each source is associated with a catalog of items. The system retrieves user data describing interactions by the user with items available at the sources and accesses and applies a machine-learning model to predict a user engagement score for each item-source pair associated with the sources based on the user data, in which the score indicates a likelihood of an interaction by the user with an item available at a source. The system selects a set of item-source pairs based on the scores and generates the user interface including the listing and a selectable option to add an item associated with each selected pair to a shopping list. The system then sends the user interface to the client device.

This invention proposes a method, system, and apparatus for rapid data backup and recovery based on CDM technology. The method includes: dynamically creating semantic copies of the business system, generating semantically typed virtual copy data, assigning unique business identifiers to the semantically typed virtual copy data according to business continuity requirements and data importance levels, and constructing a semantically guided copy directory system; it belongs to the field of data backup technology. Through this rapid data backup and recovery method based on CDM technology, the efficiency of data backup and recovery is significantly improved, achieving second-level RPO and minute-level RTO, and greatly shortening business interruption time.
