Eric Secules updated NIFI-14712:
--------------------------------
Description:
Background: I have a very large flow with 50000 or so processors and the
flow-analysis endpoint is taking 20 or more seconds to complete. This is likely
because the endpoint is traversing all the process groups recursively each time
it is called.
This endpoint also holds a read lock on the flow for the entire time, so it
will prevent any writes.
Suggestions:
# Short circuit this endpoint and return a default success value if there are
no violations at all.
# Only show detailed validation errors for the current process group and not
descendants in the UI. For process groups within the current process group,
show a cumulative count of violations within each process group. Counts would
be updated lazily.
