Apache Druid

You have to set these server properties on different historicals, then it should show up correctly.

If both settings are in the same config file, the historical will only pick the latest config in the property file (based on your observations)

I used <https://druid.apache.org/docs/latest/tutorials/index.html> to set up local env and using start-micro-quickstart to run server

This doc mentions that the properties should be in historical/runtime.properties .. so I need to create folders under historical to create multiple runtime.properties ?
<https://druid.apache.org/docs/latest/operations/mixed-workloads.html#historical-tiering>

ah I see, the quickstart runs only 1 historical server. To test multiple tiers, you will need to run at least 2 historical servers, either locally, or elsewhere.

You can see the `bin/start-cluster-data-server` as an example script to start just the data server. The conf file for the historical that this script starts is in `conf/druid/cluster/data/historical`
