Simon Bence created NIFI-8039: --------------------------------- Summary: Decrease the initial resource reservation of Listen processor family Key: NIFI-8039 URL: https://issues.apache.org/jira/browse/NIFI-8039 Project: Apache NiFi Issue Type: Bug Components: Extensions Reporter: Simon Bence Assignee: Simon Bence Fix For: 1.13.0
ListenTCP processor and other processors in the listen family are reserve resources at initialisation based on properties on the processor. This includes: * Executor in SocketChannelDispatcher is created using fixed thread pool * Byte buffer pool is build up based on Max Number of TCP Connections which with high connection can consume high amount of memory In some use cases this is undesirable and might even cause failure of the initialisation. In order to avoid this I suggest to remove the buffer pool and replace the fixed thread pool into a more flexible (scaling) implementation. -- This message was sent by Atlassian Jira (v8.3.4#803005)
