2.3.2 Execution order of I/O Plugins
When you develop multiple I/O Plugins, we recommend you make sure that they are independent of any other plugin processing.
However, in case multiple I/O Plugins are placed in the same node, you can specify the execution order in an I/O Plugin XML file so that they are executed in the specified ascending order. You can specify the execution order for each plugin, but cannot specify the execution order of methods within a plugin.
