Jeff Storck updated NIFI-4872:
------------------------------
Issue Type: New Feature (was: Test)
> NIFI component high resource usage annotation
> ---------------------------------------------
>
> Key: NIFI-4872
> URL: https://issues.apache.org/jira/browse/NIFI-4872
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework, Core UI
> Affects Versions: 1.5.0
> Reporter: Jeff Storck
> Assignee: Jeff Storck
> Priority: Critical
>
> 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.
