Abstract: Embodiments of an overlay network with innovative virtual network switches and related network interface controllers are disclosed. According to one embodiment, the overlay network may comprise at least one virtual network switch (VNS), wherein each VNS is installed within a corresponding first processing endpoint which is logically above a network of virtual machines. And, the VNS may be configured to intercept data packets transmitted on a network layer logically below the network of virtual machines. The VNS may comprise: (a) a manager element configured to connect to at least one virtual network interface controller (VNIC), each VNIC being installed within a corresponding second processing endpoint which is also logically above the network of virtual machines; (b) a replicator node configured to replicate and route the data packets; and (c) a switch controller configured to control the first replicator node.

Abstract: Techniques for using finite state machines (FSMs) to implement workflows in a data processing system comprising at least one data store storing data objects and a workflow management system (WMS). The WMS is configured to perform: determining a current value of an attribute of a first data object by accessing the current value in the at least one data store; identifying, using the current value and metadata specifying relationships among at least some of the data objects, an actor authorized to perform a workflow task for the first data object; generating a GUI through which the actor can provide the input that the workflow task is to be performed; and in response to receiving, from the actor and through the GUI, input specifying that the workflow task is to be performed: performing the workflow task; and updating the current workflow state of the first FSM to a second workflow state.

Abstract: In a processing system, an identifier for a current version of code for an application is published in a message to a shared event stream. Any instances of the application within the processing system may update to the current version before processing other messages having sequence numbers after the message containing the identifier. In this manner, multiple instances of the application may be periodically updated to maintain global consistency of the application and the shared event stream.

Abstract: Embodiments of the present invention provide a novel system and method for TCP-to-multicast (T2M) communications. The T2M techniques may allow a client to make a single TCP connection that then fans out into communications with multiple back-end resources. Such one-to-many communications may be invisible to the client but can achieve many practical benefits.

Abstract: A method implemented by a data processing system for enabling a system to pipeline or otherwise process data in conformance with specified criteria by providing a graphical user interface for selecting data to be processed, determining metadata of selected data, and, based on the metadata, automatically processing the selected data in conformance with the specified criteria.

Abstract: A method implemented by a data processing system for: enabling a user to preview attributes of fields of an expanded view of a base dataset and to specify one or more of the fields to use in downstream data processing and generating a dataset that includes the one or more of the fields from the preview specified to be used in the downstream data processing, with the generated dataset having increased efficiency with respect to speed and data memory, relative to an efficiency of generating a dataset including all the fields of the expanded view when only the specified one or more of the fields are used in the downstream data processing.

Abstract: Communication techniques are disclosed for a distributed computing system. The technique may be applied to an inline clearing and settlement messaging protocol whereby a matching engine may issue a transaction request (or settlement request) upon matching a proposed trade, identifying the parties and assets for the trade. A message gateway may validate and transmit the transaction request to a sequencer which sequences the transaction request into a time-accurate event stream so that transaction requests are distributed to relevant parties in chronological order. Each party may respond to the transaction request by simply checking its account to confirm availability of the relevant asset for the proposed trade and issuing a clearance response. The clearance responses form the basis for a transaction response that the message gateway sends to the matching engine to indicate success or failure of the inline clearing and settlement.

Abstract: A method for using a metadata model to perform operations on data items, with the metadata model including parent nodes and child nodes connected by edges, with the parent nodes specifying logical metadata and the child nodes specifying physical metadata representing the data items, and with the edges specifying relationships between the nodes. The method includes: identifying a given data item and physical metadata of that given data item, accessing the metadata model, identifying, in the metadata model, a child node representing the physical metadata of the given data item, traversing one or more edges in the metadata model to identify parent nodes of the child node, determining, from logical metadata associated with the identified parent nodes, one or more operations to be performed on the given data item, applying the one or more operations to the given data item to transform the data item, and storing the transformed data item.
