Verified history
This means HyperObserve has not found sufficient first-party evidence for a dated before-and-after event. It does not mean Redis has never changed. Undated values are kept in the current baseline below instead of being presented as history.
Current monitored baseline
HyperObserve currently monitors 3 scoped observations for Redis. The baseline covers maximum connected clients, single string value, reserved descriptors. Each value retains its plan, product, endpoint, region, account, or runtime qualifier so a future change can be compared against the correct scope.
| Constraint | Current value | Scope | Verified source |
|---|---|---|---|
| maximum connected clientsRedis lowers the effective value when the operating-system file-descriptor limit is insufficient. | 10,000 default | Redis 2.6+ | RedisAug 22, 2026 |
| single string valueStrings can contain binary data, but very large values affect latency, memory, replication, and persistence. | 512 MB | Redis default | RedisAug 22, 2026 |
| reserved descriptorsRedis reserves descriptors for internal use when determining effective client capacity. | maxclients plus 32 file descriptors | Redis server | RedisAug 22, 2026 |
Tracked constraints and impact
Configurable client connections, string size, file descriptors, and buffer limits. A change is recorded only when it alters a constraint developers can act on, such as capacity planning, request shaping, model selection, deployment configuration, storage design, retry behavior, or account budgeting.

How a change is verified
- Compare the current first-party statement with the previously stored observation, including the exact plan, model, runtime, endpoint, region, and account scope.
- Separate a true product change from documentation clarification, temporary capacity, configurable account state, or a limit that applies to a different execution path.
- Preserve the old and new values, official source, effective date when disclosed, detection date, and practical impact. If those elements cannot be supported, no historical event is published.
Official sources monitored
These first-party documents support the current Redis baseline. HyperObserve links directly to them so you can confirm the live wording before making a production decision.
