Subject [jira] [Created] (HIVE-14467) Translate Druid query back from Calcite plan
Date Mon, 08 Aug 2016 11:48:20 GMT
Jesus Camacho Rodriguez created HIVE-14467:

             Summary: Translate Druid query back from Calcite plan
                 Key: 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.
