# UpdateManagedTableRequest
## Properties
**constant_per_key** | Option<**Vec<String>**> | Columns whose value is the same for every row sharing this table's key. Send `[]` to revoke the declaration, which restores the unrestricted search on the next load — this is the kill switch if a declaration turns out to be false. **Correctness-affecting, not a hint.** If the assertion is false, a keyed mutation supersedes one version of a key and appends beside another, silently duplicating it. | [optional]
