Abstract: Systems and methods for real-time message processing and control loop feedback are described. A stream processing system includes (i) a publish/subscribe and message queueing subsystem and (ii) an execution subsystem. A real-time stream of transactions is received at the publish/subscribe and message queueing subsystem. A job is created to aggregate data from the real-time stream of transactions with data from one or more other streams received at the publish/subscribe and messaging queueing subsystem. The job is executed at the execution subsystem, and the aggregated data resulting from the execution of the job is received at the publish/subscribe and message queueing subsystem. At least a portion of the aggregated data is provided as input to a control loop feedback process, which is executed to generate a result.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying a plurality of auction elements, each auction element comprising one or more ad spaces on web pages, identifying an advertising element, the advertising element comprising an advertiser and one or more campaigns, each campaign comprising one or more creative elements, submitting the advertising element to bid on available ad spaces of the auction elements during a first time period, using a respective first bid price for each particular auction element, determining a first budget spending pace of the advertising element for the first time period based on a number of impressions served by one or more creative elements of the advertising element on the auction elements during the first time period, determining a target budget spending pace of the advertising element for a second time period after the first time period, and determining a second bid price for each particular auction element for the s
