> 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.
