@maartenbreddels For the record: > null values comparison fail, no idea what the issue is there, quite difficult for me to debug I am not sure what was causing this, but my small rewrite of the kernel fixed it. > I think kernels should have the option to opt-in at least, so we can return an empty struct (all its arrays of length 0), but with field names. This was solved by defining a `Resolver` function so that the FunctionOptions instance can participate in output type resolution (instead of specifying an empty struct type when declaring the kernel). -- This is an automated message from the Apache Git Service.
