Concurrent Prefix Recovery: Performing CPR on a Database

Summary: CPR replaces WAL group commit with asynchronous incremental checkpointing for scalable durability. It provides semantic commit windows per session ('all ops up to ti') while preserving point-in-time consistency; validated on in-memory DB and FASTER with hundreds of millions of ops/sec.
