Wiktor Kubicki updated NIFI-9465:
---------------------------------
Description:
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 better 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.
