Abstract: Techniques for a service provider network to communicatively couple services and/or applications in a serverless computing environment. A pipe component can configure a pipe to integrate two services by transmitting data between services and/or applications using the pipe. The pipe may also be configured to transform how a service processes an event, control timing of event transmissions using the pipe, define an event structure for an event, and/or batch events. Pipes enable an application or service to exchange data with a variety of services provided by the service provider network while controlling what type of data is generated, stored, or transmitted.

Abstract: A lock-free implementation of an ordered data structure allows updating of the data structure without disturbing the ordering relied upon for accessing the data structure. After searching and finding an element in a data structure in accordance with an update operation (i.e., an insert operation or a remove operation), values are successively copied to shift the values either up or down the data structure. If an insert operation is being performed, then the new value is eventually inserted to overwrite a duplicate value in the data structure. If a delete operation is being performed, then a value is shifted over the value to be deleted.

Abstract: A method for describing objects in a virtual space. In one embodiment, each object is a URL, which has been assigned to a system of hierarchical categories. The objects have been mapped to a map region, each object having been given a location within the map region. Each category within the map region is defined as a polygon area covering all of the category's objects as well as all of the category's subcategories. A client computer can request a portion of the map to be visualized. A host computer receives the request and retrieves the appropriate objects and categories from a database. The host computer forms the response to the request using a protocol which describes facts, location, and metadata about the objects and categories. The encoded response is delivered to the client. The client decodes the response and renders the objects and categories for the user. Different types of clients can concurrently request object descriptions from the server.
