* Broker load supports function 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.
