I agree with Nic here...it seems like there are constraints: notably there is no current way that I know about to compute a unique row identifier to group by. The workaround you proposed would certainly work...another one that might work more generically is a user-defined function (which could use the happy accident that R is single threaded and could therefore produce unique values). Both of those workarounds have performance implications and would introduce maintenance overhead. That might be worth it for a feature that has high user payoff...is there a motivating example that illustrates the utility of `rowwise()` on Arrow objects? -- This is an automated message from the Apache Git Service.
