FrankChen021 opened a new pull request, #17937: URL: https://github.com/apache/druid/pull/17937
A part of #17769. ### Description Allow raw sql in the HTTP body on http endpoints. This helps reduce the client side complexity which require users to do character escape when the SQL in placed in the JSON document. The following example demonstrates the usage: ```bash echo 'SELECT 1' | curl -X POST "http://localhost:8082/druid/v2/sql"; --data @- ``` #### Release note Druid now supports raw text format SQL on `/druid/v2/sql` endpoint. The content in the HTTP body of a HTTP request which does not set `Content-Type` to `application/json` will be treated as a raw sql text. ##### Key changed/added classes in this PR 1. Only HTTP requests with `Content-Type: application/json` will be parsed as traditional JSON format SQL 2. All other HTTP requests including those with empty Content-Type will be parsed as raw SQL 3. Router also supports raw text SQL, but when it forwards query to brokers, it uses the JSON format for simplicity implementation <hr> <!-- Check the items by putting "x" in the brackets for the done things.
