Thanks @yjshen Some other notes 1. We had a `Vec<u8>` based implementation prior to https://github.com/apache/arrow-datafusion/pull/808 which I think @Dandandan originally contributed (see the `create_key_for_col` function) 2. the `ScalarValue` overhead is actually worse than 16 bytes: it is `48` or `64` depending on architecture 😱 : https://github.com/apache/arrow-datafusion/blob/e92225d6f4660363eec3b1e767a188fccebb7ed9/datafusion/src/scalar.rs#L2301-L2309 -- This is an automated message from the Apache Git Service.
