Subject Optimizing Performance of Apache NiFi's Network Listening Processors
Date Fri, 02 Aug 2019 10:28:03 GMT
Hello All,

I need to listen to and process thousands of persistent TCP connections. I
have 10 nodes, each having 8 cores.
My understanding is that with existing NiFi listening processors, such as
ListnSyslog, a thread is utilized for each TCP connection. Does this scale?
Do I need to write a custom processor that utilizes a thread pool for
reading the data from the socket and processing them?
