             Summary: NIFI component high resource usage annotation
                 Key: NIFI-4872
             Project: Apache NiFi
          Issue Type: Test
          Components: Core Framework, Core UI
    Affects Versions: 1.5.0
            Reporter: Jeff Storck
            Assignee: Jeff Storck

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.
