JetGraph vs Redis
In-memory is not the same as a graph engine
Redis excels at keys, counters, sorted sets, and caches. JetGraph excels at typed relationships plus those time signals together.
Where Redis is the better tool
- Session cache, rate-limit counters, leaderboards, queues, pub/sub
- You only need INCR on a key and have no multi-entity relationships
- You already have a mature Redis operations practice and no graph queries
Where JetGraph is the better tool
- The feature is defined by edges (shared device, first-time merchant, neighbor fraud)
- You need Cypher MATCH or neighbor lists, not only a string key
- Risk propagation across a neighborhood should be an engine operation
- You want velocity windows maintained with the graph, not a pile of Redis keys you must keep consistent yourself
You might use both
Redis for application cache and idempotency keys; JetGraph for the fraud/identity graph. JetGraph is not a Redis protocol server.
