@HeartSaVioR, I think Spark should always pass an explicit null order to data sources. For example, `SortOrder` in the public expression API that is supposed to be passed to data sources always has a null ordering. Where this PR can be handy is if we want to support defining distribution or ordering in SQL statements (e.g. table creation). Then if the user just says `ASC`, we will parse it `SortDirection.ASC` and take the default null ordering. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
