Brendan updated NIFI-10510:
---------------------------
Priority: Minor (was: Major)
> 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
> Priority: Minor
>
> 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.
