Pick a NoSQL Store for an Event-Stream Sidecar Cache
Overview
What this challenge is about.
Set up identical 3-node clusters of Redis 7, KeyDB, and DragonflyDB on equivalent hardware. Run the team's captured 24-hour workload trace (around 180k ops/second, 80/20 read/write, average value 2.1 KB). Measure p50/p99 latency, throughput, memory efficiency, and CPU under sustained load. Compare operational properties (replication semantics, failover, snapshotting). Deliver a benchmark report, a 6-page decision memo, and a 4-week deployment plan for the chosen store.
The Brief
What you'll do, and what you'll demonstrate.
Benchmark Redis vs KeyDB vs DragonflyDB on a real 24-hour workload trace and recommend one with a 4-week deployment plan.
Earning criteria — what you'll demonstrate
- Benchmark NoSQL stores on a real workload trace, not synthetic loads
- Reason about operational properties beyond raw latency numbers
- Write a decision memo with explicit revisit triggers
- Plan a phased cache deployment behind a feature flag
