----------------------------------------
Summary: Support a function to flatten a nested schema
Key: HIVEMALL-88
URL: https://issues.apache.org/jira/browse/HIVEMALL-88
Project: Hivemall
Issue Type: Improvement
Reporter: Takeshi Yamamuro
Since parquet is first-citizen in Spark, most of users use nested schemas in
DF. In some usecases, they need to flatten nested schemas into flat ones to
dump data into the other systems that do not support nested schemas, e.g.,
RDBMS. So, it is useful to support conversion function from nested schemas to
flat ones.
