Hi #there! What is the best approach to enable multi-stage query engine when using docker-compose?

You can enable it via REST APIs or via the query UI:

<https://docs.pinot.apache.org/developers/advanced/v2-multi-stage-query-engine#via-rest-apis>

so the the following isn't required in v0.12? https://docs.pinot.apache.org/developers/advanced/v2-multi-stage-query-engine#how-to-enable-the-multi-stage-query-engine

The

GET /cluster/configs

output will show if it is enabled
