Commit 0b9f2fbe3bd3739d1df22623b347b3b514242191 in nifi's branch
refs/heads/main from Mark Payne
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=0b9f2fb ]
NIFI-7678: Fixed memory leak, improved some logic that constantly created
collections unnecessarily. Changed types of Collections being used to much more
efficient implementations. Removed using Streams for performance-critical parts
of application
NIFI-7678: Check if debug is enabled before logging message about
processor.onTrigger because obtaining class name is expensive
Signed-off-by: Pierre Villard <[email protected]>
This closes #4431.
> Stateless NiFi does not properly manage process sessions, leading to memory
> leak and poor performance

> Time Spent: 20m
> Remaining Estimate: 0h

> Stateless NiFi keeps track of all created Process Sessions and holds them in
> memory without ever releasing them, instead of removing them from a List
> after the processor completes. This results in very poor performance and will
> eventually exhaust the heap
