benbellick opened a new issue, #1498: URL: https://github.com/apache/arrow-go/issues/1498
`arrow/compute/exprs` currently [represents unsigned Arrow integers as signed Substrait integers with Arrow-specific type variations](https://github.com/apache/arrow-go/blob/32947b259414a77ae6347d3d29bd69ec00b9d560/arrow/compute/exprs/types.go#L637-L672). Substrait now defines standard [`u8`, `u16`, `u32`, and `u64` extension types](https://github.com/substrait-io/substrait/blob/ecb826b53abdd11f42093efcf1d687ca9670a0b0/extensions/unsigned_integers.yaml#L3-L31) under `extension:io.substrait:unsigned_integers`. Once these extensions are supported in a released version of `substrait-go` that Arrow can adopt, we should use them for unsigned integer conversion and literals instead of the Arrow-specific variations. This would let consumers recognize the types without knowing Arrow's convention. The migration should also consider compatibility with existing expressions using the old representation. -- This is an automated message from the Apache Git Service.
