> This is similar with https://issues.apache.org/jira/browse/SPARK-16351.
> Currently, {{JdbcUtils.savePartition}} is doing type-based dispatch for each row to write
appropriate values.
> So, appropriate writers can be created first according to the schema, and then apply
them to each row. This approach is similar with {{CatalystWriteSupport}}.
