Abstract: Technologies are described for adaptive selection of user to database mapping. An impact to processing resources by a user of a database managed by the processing resources may be predicted using criteria based on user-database properties such as a number of rows in database, a number of rows in database for the user, a maximum depth of hierarchy for the user, a maximum breadth of hierarchy for the user, applications that have recently accessed the user's data, distribution of quota types in the user's data, a number of shared items in the user's hierarchy, a number of people who share in the user's shared item hierarchy, an application employed by the user to access the data currently, etc. Based on a model for the predicted impact, a behavior change (for any of the criteria) and/or a move of the user to another database may be suggested/automatically implemented.

Abstract: A connector assembly for supplying power and transmitting signals from a vehicle to a towed trailer or other towed equipment. The connector assembly comprises a trailer hitch having a cross tube extending horizontally behind the vehicle. The cross tube has a wall separating an inside cavity from an outside surface of the cross tube. A first connector attached to the outside surface or mounted in a first opening in the wall of the cross tube has a connecting portion outwardly of the outside surface. Likewise, a second connector mounted at the outside surface or in a second opening in the wall of the cross tube has a connecting portion outwardly of the outside surface of the trailer hitch. One or more conduits extend across the inside cavity between the first and second connectors for interconnecting the vehicle to the towed trailer for supplying power and transmitting signals between them.
