If this is not a hadoop load, do we need to call this function ?

Actually, the columnToFunction is also used by the check function.
The check function is mainly used for checking the correctness of column expr.
Example: the column which is not defined in columns and column mapping has default value or not.
So maybe the columnToFunction still has been used in hadoop and broker load.
The annotation of columnToFunction need to be changed.

The commit support the column function in broker load. The grammar of LoadStmt has not been changed. Example: columns terminated by ',' (tmp_c1, tmp_c2) set (c1=tmp_c1+tmp_c2) Also, the old function is compatible such as default_value, strftime etc. After this commit, there are no difference in column function between stream load and broker load except old function.
