cloud-fan commented on issue #23171: [SPARK-26205][SQL] Optimize In for bytes, shorts, ints URL: https://github.com/apache/spark/pull/23171#issuecomment-447611201 I think what we can do is: 1. add a new config `optimizeInWithLiteralList`, if it's true, turn `In` to `OptimizedIn` if list is all literal. 2. `OptimizedIn` has a parameter `inSetThrehold`, which is passed when constructing `OptimizedIn`. The `inSetThrehold` decides whether we want to use switch based optimization or hash set.
