**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Rationale make it as easier (more ergonomic) to implement array comparison, both for DataFusion and other users. See rationale in https://github.com/apache/arrow-rs/issues/843 **Describe the solution you'd like** The idea would basically be to implement the same thing as @viirya did for timestamp types in https://github.com/apache/arrow-rs/pull/1095 but for `DecimalArrays` That is the following code should not assert and compare the decimal arrays element by element: ```rust let arr1: DecimalArray = ...; let arr2: DecimalArray = ...; let result = eq_dyn(&arr1, &arr2); assert!(result.is_ok()) ``` **Describe alternatives you've considered** For completeness, we could also add `eq_decimal`, `neq_decimal`, etc as well, though I personally think focusing on the dyn kernels would be the easiest thing. **Additional context** @liukun4515 has added kernels in DataFusion here which could be adapted https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_plan/expressions/binary.rs#L80-L231 other context: I am trying to move datafusion over to using the dyn kernels here: https://github.com/apache/arrow-datafusion/pull/1475 -- This is an automated message from the Apache Git Service.
