Agreed, real `TopKExec` would be fantastic (actually I was convinced that this was already implemented in 28.0.0 after a cursory code/PR glance, hence my original issue #7149). That said, that may take some time, and this PR feels to be on the verge of breaking even when it comes to performance and thus serve as a bandaid/base case until the real thing is implemented. So I'm compelled to continue experimenting with a couple of related approaches (i.e. things along the line of @Dandandan's batched eager sorting) for a short while if you don't mind (and share if I find something promising). -- This is an automated message from the Apache Git Service.
