Thanks for the extra details, the frontrun benchmark numbers seem compelling for various cold-read use cases.

A system that combines both WAL frames with cold-read-optimized grouped pages is another interesting point in the design-space. Tuning the intervals separately could make it work well- frequent WAL-checkpoint uploads, and grouped pages only on higher-level compaction cycles for cold-read optimization on longer-lived objects.

Looking forward to seeing where you head with this!
