----------------------------------------------
Summary: Support different types for grouping columns in GroupBy
Druid queries
Key: HIVE-16751
URL: https://issues.apache.org/jira/browse/HIVE-16751
Project: Hive
Issue Type: Bug
Components: Druid integration
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Calcite 1.13 pushes EXTRACT and FLOOR function to Druid as an extraction
function (cf CALCITE-1758). Originally, we were assuming that all group by
columns in a druid query were of STRING type; however, this will not true
anymore (result of EXTRACT is an INT and result of FLOOR a TIMESTAMP).
When we upgrade to Calcite 1.13, we will need to extend the DruidSerDe to
handle these functions.
