A system and method of bootstrapping replicas from existing partitions is disclosed. A distributed database is maintained by a system. The distributed database includes a first partition copy and a second partition copy each containing a database. A failure of the first partition copy is detected and a third partition copy including an empty database is generated. The database of the second partition copy is copied to the empty database of the third partition copy and the third partition copy is designated as one of an active partition copy or a replica partition copy.

System and method for bootstrapping replicas from active partitions

This application relates to apparatus and methods for automatically determining and providing digital advertisements to targeted users. In some examples, a computing device receives campaign data identifying items to advertise on a website, and generates campaign user data identifying a user that has engaged all of the items on the website. The computing device may then determine a portion of the users based on a relationship between each user and the campaign user data, and may determine user-item values for each of the items for each user of the portion of users, where each user-item value identifies a relational value between the corresponding user and item. The computing device may then identify one or more of the items to advertise to each user of the portion of users based on the user-item values, and may transmit to a web server an indication of the items to advertise for each user.
