-----------------------------------
Summary: RetryFlowFile
Key: NIFI-6387
URL: https://issues.apache.org/jira/browse/NIFI-6387
Project: Apache NiFi
Issue Type: Improvement
Reporter: Travis Neeley
Processor takes a FlowFile. It will then look for a retry attribute on the
FlowFile. If none is present or if the designated retry attribute is set and
not a number, the retry attribute is set to "1" and passed to a retry
relationship.
A configurable PropertyDescriptor contains the maximum number of times the
FlowFile can be retried before being passed to a separate retries exceeded
relationship. This PropertyDescriptor should have a validator for allowable
positive integers for the retry.
Processor may also conditionally penalize the FlowFile on the retry
relationship.
Many interactions with NiFi request some information from a service and retry
if the response isn't explicitly success. While it's quite common to use
UpdateAttribute followed by a RouteOnAttribute to do this, there could be value
in having a discreet processor for this.
