Hi,
I need to generate unique numbers globally across NiFi nodes in an atomic,
persistent way. Ideally, something like a sequence but with no actual database
involved.
Maybe I'm missing something here, but I don't think a Distributed Map Cache,
like described in Use of Sequence in Nifi without using a custom processor, is
a solution. How would that prevent concurrent access issues?
Counters don't help either because they only keep values in memory, right?
Do I need to create my own specialized Controller Service?
Thank you,
Marcio
