Systems, methods, and computer-readable media are disclosed for an improved database. The systems, methods, and computer-readable media described herein may enhance the response time of databases and improve user experiences. In an example method described herein, a database monitoring system may receive instructions to perform one or more data monitoring operations comprising counting an occurrence of a first value within at least a portion of items stored in a database. The method may include determining a length of a first window of time and fetching, from a first location of a data store of the database, data indicative of a total count of the occurrence of the first value at a time associated with the beginning of the first window of time. In turn, the monitoring system may store data representing the first count in the first memory.

Systems, methods, and computer-readable media are disclosed for an improved database. The systems, methods, and computer-readable media described herein may enhance the response time of databases and improve user experiences. In an example method described herein, a database monitoring system may receive instructions to perform one or more data monitoring operations comprising counting an occurrence of a first value within at least a portion of items stored in a database. The method may include determining a length of a first window of time and fetching, from a first location of a data store of the database, data indicative of a total count of the occurrence of the first value at a time associated with the beginning of the first window of time. In turn, the monitoring system may store data representing the first count in the first memory. The, monitoring system may determine that the first count of the occurrence of the first value changed during the first window of time and store data representing the second count in the first memory. Once the monitoring system determines that the first window of time expired, the monitoring system may provide, to the database, the data representing the second count from the first memory, wherein the database is configured to initiate a write operation for storing the data representing the second count at the first location of the data store of the database.

Systems and methods are disclosed that use social networking profiles of users to generate personalized content of display pages. The personalized content may be generated using profile data retrieved via an application program interface of a social networking system, and may be presented on the display pages of a distinct system, such as a site that hosts an electronic catalog of items. The personalized content may include features that allow a user to indicate a like or preference for an item and that can be customized based on, e.g., the extent of the user's social network or the influence the user has over other potential users of the catalog system. Systems and methods are also disclosed that use the social networking profiles to generate personalized messages that can be posted to social network contacts of the user to provide information about items for which the contacts may be interested.
