------------------------------
Summary: Process Group Inbound and Outbound Strategies
Key: NIFI-10510
URL: https://issues.apache.org/jira/browse/NIFI-10510
Project: Apache NiFi
Issue Type: New Feature
Reporter: Brendan
The current process group has as options for "{*}single batch per node{*}" or
"{*}single flowfile per node{*}" and "{*}batch output{*}" options for inputs
and outputs however this is only honored within the scope of that group
processor and once a flow enters a child process group it is not kept.
There is a usecase where on the parent level you have a single flow in then it
splits and goes into additional process groups etc and you want to wait for it
to complete all the way down and come back up to the parent level and then
release that as a batch output from that 1 file that entered.
This request is for an option to allow for single in which honors it for the
nested process groups and a batch output that also honors this as sometime we
batch logic and one flow follows a certain path and the next another and these
are grouped logic sets but you want to leverage the process group rules on a
highlevel that follows through all the way into the nested ones... the nested
process groups would still have their own input/output strategy but the parent
with the option to apply on nested children will wait until all works is done
on all levels.
