This node allows the option to return null during the node configuration. This may be of benefit when using loops, during each iteration
of a loop all connected nodes are configured (inside and outside of the loop). This causes unwanted overhead for executing complex loops.
You can use this node to prevent the execution of the configure methods. This can be disabled to allow you to build your workflow and configure downstream nodes, then either manually setup to kill the configuration or control this with a flow variable with the values 'true' or 'false'.
May also be useful for testing a nodes handling of NULL input DataTableSpec.
