Conformance over time
Where it falls short
Operation groups with gaps in the latest run, biggest first. Unsupported means the target doesn't implement that feature at all, often by design. Open one for the exact tests, or see the conformance suite.
-
backups Tier 2 unsupported
View these tests in the suite →- Continuous backups — PITR reports PITR DISABLED by default
- Continuous backups — PITR enabling PITR transitions PointInTimeRecoveryStatus to ENABLED
- On-demand backups — lifecycle and restore CreateBackup → DescribeBackup → ListBackups → DeleteBackup
- On-demand backups — lifecycle and restore RestoreTableFromBackup initiates a restore into a new table
- On-demand backups — lifecycle and restore DescribeBackup on a deleted backup throws BackupNotFoundException
