3. Some actual guarantee that you can use to feel safe in the service, even if that guarantee is much smaller and less miraculous than the PR would suggest.

- cavisne 8y agoThe marketing message could be clearer here but if you read the aurora paper https://www.allthingsdistributed.com/files/p1041-verbitski.pdf https://www.allthingsdistributed.com/files/p1041-verbitski.p... And the docs There are actually two backup/restore methods. 1) Point In Time - streamed to S3. Guaranteed restore to a new cluster with less than 5 minutes data loss 2) Aurora Backtrack - On cluster buffer, up to 24 hours retention (no guarantee). "Instant" restore to the same cluster So you should feel safe using the service (up to the 5 minute worst case scenario). Obviously no one would ever want to use either backup method. However previously disaster recovery would involve spinning up a new cluster, deploying application changes with the new endpoint (or in a best case repointing a dns entry), waiting for the cache to warm up again. Now it becomes a 1 click fix through the UI with no application changes.
