Summary: Implement UDF to expand Map vector into a RepeatedMap containing Key, Value pairs
Key: DRILL-1534
URL: https://issues.apache.org/jira/browse/DRILL-1534
Project: Apache Drill
Issue Type: Bug
Reporter: Mehant Baid
Assignee: Mehant Baid
Consider the following JSON:
{
"x": {
"y": "kevin",
"z": "paul"
}
}
Now this UDF would transform the map 'x' in the following manner
[{"key":"y","value":"kevin"},{"key":"z","value":"paul"}]
