---------------------------------
Summary: NIFI component high resource usage annotation
Key: NIFI-4872
URL: https://issues.apache.org/jira/browse/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.
