Let me move the conversation to a new issue. I agree with @jorgecarleitao that we could introduce an API in addition to current Aggregator to provide the functionality - the current `sort` actually does exactly that. And to @alamb 's point performance and memory consumption would be an issue, we may need to handle spilling to disk. As said, I'll create a new issue for this. For the sake of this task, I suggest we close with the approximation version, what do you think? @matthewmturner are you comfortable using the approximate version for your benchmark work? -- This is an automated message from the Apache Git Service.
