beliefer commented on issue #24372: [SPARK-27462][SQL] Enhance insert into hive table that could choose some columns in target table flexibly. URL: https://github.com/apache/spark/pull/24372#issuecomment-495663042 @mgaido91 Thanks for your review here.This PR only implement for Hive. Because I want we could focus on this point. If Spark allows implement for other data source, I will open other PR to implement. AFAIK, some data source support the syntax, such as Hive, MySql and Oracle. But some data source not support the syntax, such as ElasticSearch, Redis and so on. So I tend to implement for Hive, JDBC, text, parquet, orc. Give the rights of implement for other data source to a third party, we can throw an unsupported exception default.
