> Vectorized Coalesce uses BytesColumnVector.setElement which does not set the
> output string length correctly.
> {noformat}
> create table str_str_orc (str1 string, str2 string) stored as orc;
> insert into table str_str_orc values (null, "X"), ("0", "X"), ("1", "X"),
> (null, "y");
> EXPLAIN
> SELECT
> str2, ROUND(sum(cast(COALESCE(str1, 0) as int))/60, 2) as result
> from str_str_orc
> GROUP BY str2;
> SELECT
> str2, ROUND(sum(cast(COALESCE(str1, 0) as int))/60, 2) as result
> from str_str_orc
> GROUP BY str2;
> EXPLAIN
> SELECT COALESCE(str1, 0) as result
> from str_str_orc;
> SELECT COALESCE(str1, 0) as result
> from str_str_orc;
> {noformat}
> Produces different results when vectorized and not vectorized.
