How celld Actually Achieves RPO Zero
Published: at 11:00 AMcelld claims a recovery point objective of zero against single-node failure — no acknowledged write is lost as long as the node holding it doesn't disappear before the bucket catches up. The mechanism isn't 'wait for S3 on every write.' It's closer to synchronous peer replication, with the bucket as backstop. Here's the actual write path, in full.
