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)
