### Is your feature request related to a problem or challenge? The RightSemi/RightAnti existence probe code path (#22828) verifies each candidate build/probe pair via `JoinKeyComparator`, whose arrow `DynComparator` is a boxed closure — an indirect call per candidate pair, which also blocks inlining. We could instead specialize for joins on primitive types and do the type lookup only once per chunk. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
