Setup
- Collection
- 100,000 unchanged documents + 200 initial mutation targets
- Measured phase
- 30 seconds · 10 changes/s · 10 background queries/s
- Database
- Version 1.40.3 · 2 CPUs · 3 GiB memory
Validity checks
- Changes were submitted on schedulePassed
- Observation reads started on schedulePassed
- Background queries started on schedulePassed
- Search recall met the 95% targetPassed
- Every mutation had a valid starting statePassed
- The client dropped no mutationsPassed
- Quality queries stayed in the intended corpusPassed
- The configured search index was verifiedPassed
Measurements
| Change | First visible p95 | Confirmed p95 | Confirmed changes |
|---|---|---|---|
| insert | 35.35 ms | 106.54 ms | 100/100 |
| Replace | 31.81 ms | 104.41 ms | 100/100 |
