----------------------------------------------
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.
