Abstract: A database node selects one of a number of database mirror hosts to perform a database read query. In theory, mirror hosts store redundant database entries. In practice, some mirror hosts fail to receive or retain some entries, e.g. if a mirror host was down for maintenance, a mirror host was overburdened, etc. The health of a mirror host, quantified as a health score, represents a likelihood that an insert statement was received and retained. Health scores are generated based on health metrics—data periodically retrieved from mirror hosts used to infer how well the database was operating, e.g. a count of entries that were inserted, a count of errors encountered while the entries were inserted, etc. If the database read query specifies entries inserted during a specific time period, the mirror host may be selected based on the health scores representing that time period.

Abstract: A system, machine-readable storage medium storing at least one program, and computer-implemented method for routing a notification to at least one device of a user is provided. User preference data including usage data is obtained from a user. The usage data may relate to activity of the user on at least one device and may indicate a preference of the user in receiving notifications on the at least one device. The occurrence of a notification event is detected. In response to the detection of the notification event, a notification is communicated to the user in accordance with the user preference data. The notification may indicate that a notification event has occurred.
