Apache Druid

I copied the `payload` from the Development View in Chrome for the working SQL query in the Router, at localhost:8888

```curl --location '<http://localhost:8888/druid/v2/sql>' \
--header 'Cookie: session=eyJsb2NhbGUiOiJlbiJ9.Za6DBQ.faVXUgFs1VF8cN0NE_cJ7rdGJ6A' \
--data '{"query":"--SELECT\n--  channel,\n  --COUNT(*)\n--FROM \"wikipedia\"\n--GROUP BY channel\n--ORDER BY COUNT(*) DESC\nselect * from wikipedia\n","resultFormat":"array","header":true,"typesHeader":true,"sqlTypesHeader":true,"context":{"sqlOuterLimit":1001,"sqlQueryId":"a59b2ae2-73ca-42bb-bb42-62e777441ede"}}'```

Okay, this works:
```curl --location --request POST '<http://localhost:8888/druid/v2/sql>' \
--header 'Content-Type: application/json' \
--data-raw '{"query":"SELECT * FROM wikipedia LIMIT 10"}'```
so now back to what Postman is doing to my request.  So NEVER MIND...

Just as an explanation. The `router` based URL is only visible from within the docker compose pods. Docker compose exposes the router port 8888, on `localhost`. Glad you found the solution.
