I have to merge results of "original", REST call and sql query responses
into one flowfile/json....
The problem happens if REST call, or sql query result in empty resultset.
For example, suppose i have 3 incoming connections for Merge:
original->flowfile1/attribute1, REST->flowfile2/attribute2, SQL
query->flowfile3/attribute3
If REST call fails (error 404 - record not found), or sql call return empty
resultset - flowfiles never merged ( the origin gets stuck in input queue).
Can I found some merge strategy to solve this problem such as only origin
json would be let through? For example, is there something i can do so that
REST error would result in empty output flowfile?
Thank you...
