Mark Payne updated NIFI-4872: ----------------------------- Resolution: Fixed Fix Version/s: 1.6.0 Status: Resolved (was: Patch Available) > 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 > Fix For: 1.6.0 > > > 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 value from a fixed list of: CPU, Disk, > Memory, Network. It should also allow the developer to provide a custom > description of the scenario that the component would fall under the high > usage category. The annotation should be able to be specified multiple > times, for as many resources as it has the potential to be high usage. > By marking components with this new Annotation, we can update the generated > Processor documentation to include this fact. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
