Nice write-up and very interesting discussions! - By feeding the signature as a key to the `HashMap`, are we not hashing the original key twice? I guess this can easily be solved by setting the identity function instead of the default hasher on the `HashMap` 😃 - Too bad we cannot index into the [builder](https://github.com/apache/arrow-rs/blob/master/arrow/src/array/builder.rs), that would allow us to build the target arrow columns strait away. Can't wait for the switch to arrow2 😉 -- This is an automated message from the Apache Git Service.
