> I think the ideal budget is not based on rows / row groups, but instead on "target_buffer_memory" as that is the limiting resource that prevents infinite buffering and what will run out earlier. 👍🏻, yep this is why I chose read ahead bytes in https://github.com/apache/datafusion/pull/24086. It might be reasonable to say that we only read ahead _within a row group_ and thus setting `read_ahead_bytes = 32Gi` or something large (could be `0` or `-1`) is equivalent to `progressive_io = false` -- This is an automated message from the Apache Git Service.
