-------------------------------
Summary: Provide listing of commonly used Attributes in UI when
using Expression Language
Key: NIFI-996
URL: https://issues.apache.org/jira/browse/NIFI-996
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework, Core UI, Documentation & Website
Reporter: Mark Payne
When a user configures a Processor and uses the Expression Language, the UI
provides wonderful contextual help when Ctrl+Space is pressed. However, this
help is based purely on the Expression Language and the associated
documentation.
It would be great to see the UI provide a list of Attributes that would likely
make sense at that point in the flow.
There are lot of things to consider here. Attributes to suggest could be
derived from the entire flow, or based on Attributes that have been seen on
FlowFIles only by that Processor. Or based on the processor that introduced the
data into the flow.
Eventually, this could even perhaps be driven by some process outside of NiFi,
by running analytics against provenance data or what have you. Something like
this would be quite a bit out of scope for now, though, and would be a later
addition, but it's important to keep in mind for design considerations.
Additionally, Authorization needs to be considered when determining which
Attributes to send.
We also don't want to fill up the Java Heap, so we would need some sort of LRU
cache type of mechanism.
Also consider on restart of NiFi, or when a new processor is added to the
graph, how do we provide context there for meaningful attributes?
