> NiFi Processors currently have no means to relay whether or not they have may be resource intensive or not. The idea here would be to introduce an Annotation that can be added to Processors that indicate they may cause high memory, disk, CPU, or network usage. For instance, any Processor that reads the FlowFile contents into memory (like many XML Processors for instance) may cause high memory usage. What ultimately determines if there is high memory/disk/cpu/network usage will depend on the FlowFiles being processed. With many of these components in the dataflow, it increases the risk of OutOfMemoryErrors and performance degradation.
> The annotation should support one or more values from a fixed list of: CPU, Disk, Memory, Network.
> By marking components with this new Annotation, we can update the generated Processor documentation to include this fact.
