    Abstract: Various embodiments of a system and method for tracking service requests are described. Embodiments may include call tree generation logic configured to receive multiple request identifiers associated with a respective one of multiple service requests. Each given request identifier may include an origin identifier, a depth value, and a request stack comprising one or more interaction identifiers. The call tree generation logic may also be configured to, based on multiple request identifiers that each include an origin identifier associated with a particular root request, generating a data structure that specifies a hierarchy of services called to fulfill that particular root request. Based on one or more of the interaction identifiers and one or more of the depth values, the generated data structure may specify for each given service of the hierarchy: a parent service that called the given service, and one or more child services called by the given service.

    Abstract: A broker may be used as an intermediary to exchange messages between producers and consumers. The broker may store and dispatch messages from a physical queue stored in a persistent memory. More specifically, the broker may enqueue messages to the physical queue that are received from producers and may dispatch messages from the physical queue to interested consumers. The broker may further utilize one or more logical queues stored in transient memory to track the status of the messages stored in persistent memory. As messages are dispatched to and acknowledged by interested consumers, the broker deletes acknowledged messages from the physical queue. The messages deleted are those preceding a physical ACKlevel pointer that specifies the first non-acknowledged message in the physical queue. The physical ACKlevel pointer is advanced in the physical queue based on the relative position of corresponding logical ACKlevel pointers maintained by the logical queues.

    Abstract: Disclosed are various embodiments for scalable workflow processing. In one embodiment, a plurality of decision applications each embody a functional expression of a corresponding one of a plurality of workflow definitions. Each of the plurality of decision applications is configured to be repeatedly instantiated. A workflow execution application is configured to orchestrate an execution of each one of a plurality of workflow instances. The workflow execution application is in data communication with each instance of a respective one of the plurality of decision applications. Each of the plurality of decision applications is configured to determine a next action to be taken for respective ones of the plurality of workflow instances.

    Abstract: A plurality of redundant brokers may be used as intermediaries to exchange messages between one or more producers and one or more consumers. More specifically, one or more producers may enqueue messages to a primary broker. The primary broker then dispatches the received messages to one or more interested consumers. However, should the primary broker fail, messages enqueued by the producers may be lost, and thus delivery of such messages may fail. Accordingly, one or more backup brokers may be provided that can assume the responsibilities of the failed primary broker and dispatch copies of the messages that were enqueued by the producers to the failed primary broker.
