I think (though I did not check) that the way the concat kernel in arrow works now is that the output type is always the same as the input type. Having the concat kernel upcast the index type (e.g. from UInt8 to UInt16) if the concatenated dictionary required it would be nice for sure -- This is an automated message from the Apache Git Service.
