Disclosed are various embodiments for increasing distributed database capacity by adding new nodes while minimizing downtime. A database is partitioned among multiple nodes in a cluster. Each node stores a respective portion of the database. The portions of the database are replicated to corresponding physical standbys. For each portion, a first portion is mapped to an existing node, while a remaining portion is mapped to a physical standby. The cluster is updated to include the physical standbys as additional nodes among which the database is partitioned.

A system and method for search list pagination include sorting a set of records in an order based on a dynamic element of each of the records, and displaying the set of records in two or more pages on an interface. If the dynamic elements of any of the records changes between the display of the first page of records and the receipt of a request to display a second page of records on the interface, the method updates the ordering of the records to account for the change in the dynamic element of each of the records, and displays the second page sorted in the order. In such a manner, a user of the system or method may view each of the records sorted in the order, based on the instantaneous contents of the records.

A return request processing engine automatically approves or denies requests for authorization to return a purchased item to the seller of the item. The return request processing engine utilizes return request rules to determine whether a particular return request can be approved or denied without input from the seller. When a request is received from a buyer to return an item, the return request processing engine utilizes the return request rules to determine if the request to return the item can be automatically approved or denied without input from the seller. If the return request processing engine cannot automatically approve or deny a return request, the return request processing engine causes a message to be transmitted to the seller of the item that provides a user interface through which the seller can indicate whether the return request is approved or denied by way of a single user input.
