englefly opened a new pull request, #44023:
URL: https://github.com/apache/doris/pull/44023
### What problem does this PR solve?
this rule replaces the OrToIn expression rewrite rule.
OrToIn rule has some drawbacks, which the new rule avoids.
1. this rule is only applied to filter. the benifit of the inferred
in-predicate can be pushed down and filter data as early as possible.
2. OrToIn expression rewrite rule gennerates more unuseful in-predicates,
which can not be pushed down.
3. OrToIn rule depends expression flags which is not stable, since other
expression rewrite rule may remove those flags.
