Abstract: 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.

Abstract: A user generates a mapping script using a mapping script generation mechanism. The mapping script is in a format that allows the mapping script to be generated and maintained by a non-programmer. A mapping engine reads a mapping script, reads an incoming data structure, and generates calls to an application interface that allows the incoming data structure to interact with the application. The mapping engine is a computer program, but does not need to change with different incoming data structures and different applications. The logic for mapping between a particular incoming data structure and a particular application is encapsulated in the mapping script, which is in a format that may be easily defined and maintained by a non-programmer. The mapping script may optionally include various mechanisms including a data conversion mechanism, a literal value mechanism, a conditional logic mechanism, and a mapping script selection mechanism.

Abstract: 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.
