**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** We are trying to store UUIDs in arrow Arrays and one obvious thing to do is use `FixedSizeByteArray` However @samuelcolvin did some experiments (see https://github.com/apache/datafusion/issues/11170) and found that non obviously using `Decimal128` was actually faster than `FixedSizeByteArray` One reason for this may be that `FixedSizeByteArray` does not have special case handling in the `filter` kernel https://github.com/apache/arrow-rs/blob/f42d2420525a05a9b55461d83b359779ca5cc2a3/arrow-select/src/filter.rs#L320-L383 **Describe the solution you'd like** 1. Add special case code for `FixedSizeByteArray` 2. Add benchmark showing it is faster 3. Add unit tests for functional test coverage **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** This was pointed out by @samuelcolvin on https://github.com/apache/datafusion/issues/11170#issuecomment-2253527396 -- This is an automated message from the Apache Git Service.
