Abstract: Software is increasingly being developed as a collection of loosely coupled applications. Loosely coupled applications exchange data by publishing data to and retrieving data from a data store, such as a database, a file located on a storage cluster, etc. Data produced by one application and consumed by another is referred to as a data dependency. In some embodiments, an application's data dependencies are identified by analyzing cached query plans associated with the application. Query plans include a hierarchical representation of a query, where non-leaf nodes represent commands and leaf nodes identify data dependencies. An application's data dependencies are identified by traversing the hierarchical representation of the query. Data dependencies consumed by the application are identified by finding leaf nodes that descend from a read command, while data dependencies produced by the application are identified by finding leaf nodes that descend from a write command.

Abstract: Methods, systems, and computer storage media are provided for providing an application programming interface (“API”) for executing a query are provided. The API call, scheduling, and assignment processing engines may generate and schedule assignments, along with associated dataset portions, based on the query. Based on the assignments and datasets, the assignments may be scheduled for execution by processes of nodes in a distributed system. The API call and query may also include implementation instructions that require storing dataset portions into memory that is associated with a process executing the assignment for an in-memory database implementation. As the assignment is executed using a dataset portion that is stored on memory associated with a process, results may be stored in a file. Once each assignment has been executed and has a result file, the result files are merged to provide results of the query and API call to the user.

Abstract: Methods, systems, and computer storage media are provided for tracking an advertisement based on the advertisement's context. When an ad event is received on a client-computing device, a single URL is determined to display an item and track a context of the ad event. A first parameter related to the ad event is encoded as a HTTP header, and a second parameter related to tracking the ad event is encoded as a query parameter appended to the URL. The URL with the HTTP header is called, causing a domain server named in the URL to extract the first parameter from the HTTP header and the second parameter from the query parameter in order to determine the context of the ad. The domain server asynchronously requests tracking of the ad based on the context. Additionally, content for a landing page is received from the domain server.

Abstract: Methods, systems, and computer storage media are provided for tracking an advertisement based on the advertisement's context. The tracking, URL, HTTP header, and landing page engines may generate a single URL for both display and tracking of an advertised item, along with HTTP headers, based on an advertisement event. In response to a call of that generated URL and HTTP headers, landing page content that includes embedded middleware may be transmitted. The received URL and HTTP header may be parsed in order to extract parameters. Based on metadata associated with the extracted parameters, the URL and HTTP headers may also be augmented with additional parameters. The augmented URL and HTTP headers may be transmitted to a tracking service. As the user continues to interact with the landing page content, the embedded middleware may transmit additional URLs and HTTP headers to be augmented before transmission to the tracking service.

Abstract: Methods, systems, and computer storage media for providing unified ranking of search result items based on a user-configured ranking attribute for an item listing in an item listing platform. In particular, a unified ranking engine determines a user-configured ranking attribute for an item listing, which is used as part of a boosting model of the unified ranking engine to rank item listings. In operation, an item listing is assigned a boost factor based on the item listing having the user-configured ranking attribute. The boost factor indicates a value that is used to rank the item listing relative to the other item listings of search results item listing. The search result items include a first set of item listings that are promoted listings associated with the user-configured ranking attribute (e.g., promoted-listing ad rates) and second set of listings that are organic listings without user-configured ranking attributes.
