UDP listener and writer

Use udpListener to receive ZAPP UDP payload containers. Use udpWriter to forward payload batches to another UDP endpoint.

UDP listener

udpListener is a source component. It listens on a local UDP address, decodes ZAPP packets into payload batches, and sends those batches to configured targets.

components:
  listener:
    type: udpListener
    network: udp
    address: :9091
    allowedSources:
      - 10.0.0.0/24
    targets:
      - target: payloadProcessor
        cap: 1000
        leaky: true

Important fields:

• network defaults to udp when omitted
• address is the local listen address
• allowedSources restricts accepted sender IP addresses or ranges
• targets receives []*zapp.Payload batches

UDP writer

udpWriter is a terminal component. It serializes payload batches into ZAPP containers and writes them to a remote UDP address.

components:
  writer:
    type: udpWriter
    network: udp
    address: 10.0.0.25:9000
    publishInterval: 10ms
    maxPacketSize: 32000

Important fields:

• address is the remote UDP endpoint
• publishInterval buffers and flushes payloads on an interval when set
• maxPacketSize limits serialized UDP packet size
