[jira] [Commented] (NIFI-1215) UI exposes a slider for Run Duration even for Processors that do not support it

Joseph Witt commented on NIFI-1215:
-----------------------------------

yes please.  We should consider having a way to communicate to the user though that this could result in data loss for some processors that support this.

Take for instance the case of receiving syslog data via UDP.  If the processor is supporting batching of those messages and loses power/state/etc.. then data could be lost in that case.  It is just a fact that a given processor should make known to the user as they select the performance/reliability tradeoff.  Many I'd bet would be willing to lose 25ms worth of data to get 2x,3x,4x+ throughput increases.  But maybe not.  Key is to inform them.

Thanks
joe

> If a Processor does not have a @SupportsBatching annotation, the Processor cannot support the configurable Run Duration. However, the UI still exposes the slider, allowing the user to configure it. Instead, the UI should show the component as disable with an indicator that "This feature is not supported by this Processor"
