Advanced tab

On the Advanced tab, you can specify how the stage should run. You can specify the following properties:

  • Execution Mode. When performing a read operation, the stage runs in sequential mode by default. In sequential mode, the conductor node processes the operation. When performing a lookup operation, the stage runs in parallel mode by default.
  • Combinability mode. The default combinability mode is Auto. In Auto mode, the operators underlying the parallel stages are combined so that they run in the same process to improve performance.
  • Preserve partitioning. You can select Set or Clear. If you select Set, a read operation sends a request to the next stage to preserve partitioning.
  • Node pool and resource constraints. Select this option to constrain parallel execution to the node pools and resource pools that are specified in the grid. Use the grid to select node pools and resource pools. The selections are populated from the configuration file.
  • Node map constraint. Select this option to constrain parallel execution to the nodes in a defined node map. You can define a node map by typing node numbers into the text box or by clicking the Browse button to select nodes from the Available Nodes window.
    Note: The Advanced tab in Stage page is blank if you are using the stage to perform a direct lookup operation on a table via iWay, that is if you have selected a lookup mode of sparse.
