Tuning Recommendation
| Profile | Recommended | Why |
|---|---|---|
| broker / durability | delete | Keep delete policy for durability workloads that rely on time-based retention. Compaction removes intermediate records, which means historical point-in-time data is not recoverable — incompatible with audit/compliance replay requirements. |
