Subject [jira] [Commented] (NIFI-548) Listen UDP should support generation of a flowfile per datagram
Date Thu, 30 Apr 2015 02:34:06 GMT


Steven Youtsey commented on NIFI-548:

1. Not my design. I inherited it when porting from NiFi 2.x to NiFi 3.x. Original author is
Joe. I have made improvements and bug fixes, but kept the basic design. Yes, it's complicated.
2. It is very tuned for performance and 'blobbing', it used to be called UDPBlobber. Much
effort went into integration testing with a high volume sender.
3. If there's a better design that maintains performance and the blobbing capability yet provides
the desired datagram per flowfile, by all means have at it.

> Listen UDP presently places udp datagrams into a buffer and then once the buffer reaches
some trigger size/age it turns that into a flowfile.  There should be an option to turn each
received datagram into a flowfile.  This is helpful for cases where each datagram is a complete
object by itself but that isnt necessarily trivially demarcated if it were concatenated with
other datagrams.
