A virtual wallet system provides embedded controls to a merchant for association and display with merchant artifacts on a merchant interface. Merchant artifacts may include begin-of-purchase flow items such as coupons, and end-of-purchase flow item such as tickets. When the embedded control displayed on the merchant interface is selected by a user, a save artifact request is communicated to a virtual wallet server allowing the user to instantly save an instance of the merchant artifact to the user's corresponding virtual wallet account.

Information describing a transaction is received and a set of hierarchical documents pertinent to the transaction are identified based at least in part on the received information. The set of hierarchical documents is pruned responsive to data describing documents that a user involved in the transaction has previously accepted. Information describing the pruned set of hierarchical documents is output for presenting the pruned set of hierarchical documents to the user involved in the transaction for acceptance as part of the transaction.

A database may be virtually partitioned into virtual partitions. The virtual partitions are mapped to physical databases of a database. Data records added to the database are each assigned to a virtual partition and stored in the physical database mapped to the assigned virtual partition. The identifier generated for a data record includes an identifier of the assigned virtual partition. When additional databases are created, virtual partitions are remapped to the larger space of physical databases.

Database partitioning by virtual partitions

Methods, systems and apparatus, including computer program products, for propagating data across shards of a database system are described. According to one method, a first request that includes instructions to place a second request in a queue of a second shard is placed in a queue of a first database shard, and the change is committed to the records of the first shard. A queue processor polling the queue fetches and dispatches the first request, placing the second request in a queue of a second database shard. The second request includes instructions for making the change to the second shard. A queue processor of the second database shard polls the queue of the second database, fetches the second request, and dispatches it to make the change on the second database shard.
