sse Binding

Zilla runtime sse binding.

sse_server:
  type: sse
  kind: server
  exit: sse_kafka_proxy

Summary

Defines a binding with Server Sent Events (sse) protocol support, with server behavior.

The server kind sse binding converts inbound http request-response streams into sse request-response streams, with optionally configured retry delay.

Messages received on the sse response stream are encoded using Server Sent Events protocol, including support for custom event types and last event id.
