[jira] [Created] (HIVE-14467) Translate Druid query back from Calcite plan

Jesus Camacho Rodriguez created HIVE-14467:
----------------------------------------------

             Summary: Translate Druid query back from Calcite plan
                 Key: HIVE-14467
                 URL: https://issues.apache.org/jira/browse/HIVE-14467
             Project: Hive
          Issue Type: Sub-task
          Components: Druid integration
    Affects Versions: 2.2.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


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.
