    Description

      Once a Calcite query plan containing a DruidQuery operator has been optimized, we need to transform the plan into a physical plan. We use the JSON Druid query that will be passed to the DruidStorageHandler to infer the schema of the records coming out of the TableScan over Druid. In particular, DruidSerDe will be able to infer the schema for Druid Timeseries, TopN, GroupBy, and Select queries.
