http_server sync_response without waiting ack

[webfrank]

Hi,
as per documentation benthos, even if I put a processor sync_response, waits for ack from output. I would like to achieve an early response (with sync_response), without waiting for output ack, like fire and forget, this way the client calling the http_server does not need to wait for output processing.

Hey @webfrank 👋 I believe that should be possible if you add a buffer in the mix. Note that the sync_response processor will have to be attached to the input so it gets executed before the messages reach the buffer. The downside is that a simple buffer such as in-memory will no longer have the same delivery guarantees (if the process dies, then the messages that are still in the buffer will be lost).
