PutUDP

PutUDP 2.12.0

PutUDP is deprecated and subject to removal in subsequent releases.

Background: NIFI-16323: Limited transport size and lack of application protocol semantics

Bundle: org.apache.nifi | nifi-standard-nar
Description: The PutUDP processor receives a FlowFile and packages the FlowFile content into a single UDP datagram packet which is then transmitted to the configured UDP server. A FlowFile larger than the destination address family maximum (65,507 bytes for IPv4, 65,527 bytes for IPv6) cannot be sent as one datagram and is routed to failure without reading content. The local UDP stack may still reject smaller datagrams; those FlowFiles are also marked as failed.

Max Size of Socket Send Buffer
