Abstract: Disclosed are various embodiments involving access to guest orders in an electronic commerce application. In one embodiment, a request to access a guest account is obtained from a client. The request specifies a destination network address and an order identifier. A message is sent to the destination network address in response to verifying that the destination network address and the order identifier are associated with the guest account. The message includes a link that facilitates access to an order management function for the guest account.

Abstract: 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.

Abstract: Disclosed are various embodiments involving access to guest orders in an electronic commerce application. In one embodiment, a guest order is generated for the purchase of a product in a server based on interaction with a client over a network. The guest order is stored in a data store in isolation with respect to a plurality of user accounts and in isolation with respect to a plurality of other guest orders stored in the data store. Client access is provided in the server to order data associated with the guest order to facilitate at least one customer action with respect to the guest order.
