Wiktor Kubicki updated NIFI-9465:
---------------------------------
Component/s: Core UI
> Limit Max Thread Count in process groups
> ----------------------------------------
>
> Key: NIFI-9465
> URL: https://issues.apache.org/jira/browse/NIFI-9465
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core UI
> Affects Versions: 1.15.0
> Reporter: Wiktor Kubicki
> Priority: Minor
>
> Now we are able to set Maximum Timer Driven/Event Thread Count for whole
> instance of NiFi. It would be great if there will be possiblity to set it per
> process group.
> How it should looks?
> Thread scheduler should check running_threads_in_instance <
> instance_thread_limit*and* running_threads_in_group < group_thread_limit. Now
> there is only first part.
> Why? In multi-tenant enviroment we can limit permission but no resources like
> memory or CPU. This feature would give us a little bigger controll in that
> area and looks not very complicated to develop.
> In second hand even in single tenant, there is advantage to limit it per
> process group - we can prevent whole instance against resources saturation if
> one group works harder.
