> Prefetching IO / combining small IO requests (reducing spawn_blocking / thread switching overhead) Should we think about the interaction with `ObjectStore`? The GCS/S3/etc. implementations do range coalescing. When we do combining of small IO requests should we take into account the layout of that data so that we combine requests that would be adjacent in the data, thus maximizing block hit rates for these providers? -- This is an automated message from the Apache Git Service.
