| // Since for join hint [[SHUFFLE_REPLICATE_NL]] when having equi join conditions, | ||
| // we still choose Cartesian Product Join, but in ExtractEquiJoinKeys, it will filter | ||
| // out equi condition. Instead of using the condition extracted by ExtractEquiJoinKeys, | ||
| // we should use the original join condition "j.condition". |

There was a problem hiding this comment.
how about:
`CartesianProductExec` can't implicitly evaluate the equal join condition, here we should
pass the original condition which includes both equal and non-equal conditions.
