Redis semantic / response cache
Low-latency cache layer for near-duplicate LLM queries - often Redis behind the gateway.
TrialFinOpsNew
- Why this ring
- Pairs with gateway caching. Trial when query duplication is measurable and TTL policy is clear.
- Production risk if ignored
- Stale answers after KB updates if invalidation is missing.
- Typical effort
- weeks
- High FinOps impact
Use cases
- Support FAQ reuse
- Internal search repeats
- Cost control
Adoption steps
- Baseline duplicate rate
- Enable Redis cache
- TTL per corpus
- Invalidate on reindex
