### Is your feature request related to a problem or challenge? See https://github.com/apache/datafusion/blob/5d6146ca3fc0c0c601c11bd04ed55e6eb4327dfe/datafusion/proto/tests/cases/roundtrip_physical_plan.rs?plain=1#L3963-L3969 If you take an `ExecutionPlan` and serialize it, all occurrences of `HashTableLookupExpr` are replaced with `lit(true)`. This makes it difficult to send dynamic filters across the network. ### Describe the solution you'd like Ideally, there's some way to serialize and deserialize these expressions, potentially by serializing the seed ``` message HashTableLookupExpr { repeated PhysicalExprNode on_columns = 1; uint64 seed = 2; repeated fixed64 build_hashes = 3; } ``` ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
