Hi there,

We have a streaming/push API where we open a connection with the client and push data to the stream continuously. I tried using the polling option but doesn’t seem to work and keep running into RequestTimeoutException.

polling.pollerName(“get”)

```auto
      .every(10 seconds)
      .exec(http("request_16").get("/v2/topics/aliases2/messages?group=perf_test").headers(headers_protobuf_consume))

```

)

Is there any sample or pointers on how to use Gatling for streaming GET request APIs? Am using version 3.0.0.

Thanks!
