> Add insertInto method with byName parameter in DataFrameWriter
> --------------------------------------------------------------
>
> Key: SPARK-29615
> URL: https://issues.apache.org/jira/browse/SPARK-29615
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Hu Fuwang
> Priority: Major
> Labels: pull-request-available
>
> Currently, the insertion through DataFrameWriter.insertInto method ignores
> the column names and just uses position-based resolution. As DataFrameWriter
> only has one public insertInto method, spark users may not check the
> description of this method and assume Spark will match the columns by name.
> In such case, wrong column may be used as partition column, which may result
> in problem (eg. huge amount of files/folders may be created in hive table tmp
> location).
> We propose to add a new insertInto method in DataFrameWriter which has byName
> parameter for Spark user to specify whether match columns by name.
