Abstract: Systems and methods of determining effectiveness of a test content item in a computer network environment are provided. A data processing system can receive a request for content from a computing device and predict a test content item as a winner of a content item auction. The data processing system can assign the computing device to a test group or a control group. The data processing system can execute the content item auction, while withholding the test content item from the auction if the computing device is assigned to the control group. The data processing system can transmit the winning content to the computing device. The data processing system can identify computer network activity associated with the test content item by the computing device. The data processing system can perform additional predictions if the computing device is the subject of additional experiments regarding additional test content items.

Abstract: A method, according to one embodiment, includes receiving, at a first node of a distributed database system from one or more caller nodes of the distributed database system, a predetermined number of service tasks to add to a value in a row stored in the distributed database system at a write daemon. Additionally, a time of receipt of the predetermined number of service tasks is recorded. Further, the predetermined number of service tasks are combined to a single row in the distributed database system at the write daemon. Further still, a number of operations to attend to the predetermined number of service tasks is reduced by sending the predetermined number of service tasks to at least two bucket daemons on at least two other nodes of the distributed database system.
