+1 (binding). Can you open a PR with the spec updates? Regards Antoine. Le 04/09/2024 à 23:17, Matt Topol a écrit :
Based on various discussions among the ecosystem and to continue expanding the zero-copy interoperability for Arrow to be used with different libraries and databases (such as libcudf, ClickHouse, etc) I would like to propose that we extend the allowable bit-widths for Arrow Decimal types to allow 32-bit and 64-bit decimals. The Arrow Spec currently defines the Decimal type as a parameterized type, parameterized by the bit-width, and then just specifies that the only allowed bitwidths are 128 and 256. Thus, rather than adding an entirely new type we could simply expand what is allowed for the bitwidth field which makes the format side of this a very small change. I've uploaded a PR for adding support for this to C++ [1] and will be uploading a PR for a corresponding Go change within the next day and will respond to this thread with the link. The vote will be open for at least 72 hours. [ ] +1 - Update the Arrow Spec to allow for 32-bit and 64-bit bitwidths for Arrow Decimal types [ ] +0 [ ] -1 - Do not update the Arrow Spec to allow for 32-bit and 64-bit bitwidths for Arrow Decimal types because....
