Hello folks I am trying to evaluate pinot as a realtime data store and I am trying to consume data from aws kinesiss. Right now I am able to figure out the config and custom data transformation for the same I just wanted to rerun it from scratch. I am on macos and built pinot from source. Where does pinot store all the data and configs we create using admin ? How can i delete that and start fresh by restarting all services from scratch ?
