In using a virtual extensible local area network (VXLAN) for stream processing, a management system allocates resources for a streaming application based on an operator graph of the streaming application. The management system assigns the resources to a group of VXLAN segments based on the operator graph of the streaming application. A first processing element of the streaming application multicasts data on the group of VXLAN segments. A second processing element on a given VXLAN segment of the group of VXLAN segments receives the data. If the second processing element is an intended recipient of the data, then the second processing element processes the data. If the second processing element is not the intended recipient of the data, then the second processing element ignores the data.

Stream processing without central transportation planning

Embodiments presented herein describe techniques for performing a rolling upgrade to a distributed runtime environment that includes a cluster of computing systems. A first of a plurality of computing nodes executing a first version of a runtime environment determines a second version of the runtime environment via a registry. Upon determining that the second version is a more recent version, the first computing node retrieves an install package for the second version from a second one of the computing nodes. The first computing node installs the second version using the install package.

Rolling upgrade of a distributed application

A computer system dynamically balances a workload of a distributed computing application at runtime. A distributed computing application is monitored at runtime for the occurrence of one or more conditions, wherein the distributed computing application comprises one or more nodes that include one or more processing elements, and wherein each processing element includes one or more operators. One or more adjustments to the distributed computing application are determined. The one or more adjustments to the distributed computing application are performed at runtime. Embodiments of the present invention further include a method and program product for configuring processing elements within a distributed computing system in substantially the same manner described above.

Dynamic runtime workload balancing in a distributed computing environment

A method in a data processing system for resizing and repositioning controls in a window displayed in a graphical user interface within the data processing system. The controls include symbols, such as text that may be replaced with other symbols, such as text in a different language. In response to replacing text in the controls within a window, an amount of resizing is determined for each control this amount of resizing is an amount that is required to expand the control to contain the replacement symbol. The maximum amount of resizing is recorded after each control has been analyzed. For each control in the window, the control is resized by the maximum amount of resizing. The maximum amount of resizing may be adjusted to ensure that the window will be fully displayed within the display device. Additionally, the expansion may be limited only to controls or windows that contain text.
