Hi, team,
I've made a simple test on saga performances, with 3
* Test scenarios:*
- Disable omega(run the original business without saga)
- Enable omega and handle saga events in Redis
- Enable omega and handle saga events in PostgreSQL
* The test environment:*
- 3 VirtualBox machines as a Kubernetes cluster on a bare metal
- K8S Cluster Node info:
- Memory: 4 GiB
- CPU: 4 Cores
- Disk: SSD
*The test schema:*
- Test with JMeter, start 100 testing threads within 5 minutes, the
whole test lasts 10 minutes.
- 10% of invalid request that will cause AbortEvent and trigger
compensation.
* The test result:*
SCENARIO1(Without saga):
Total requests: 401,257, avg QPS: 668, avg Response time: 11.82 ms
SCENARIO2(Saga in Redis):
Total requests: 200,085, avg QPS: 333, avg Response time: 125 ms
SCENARIO3(Saga in Postgres):
Total requests: 132,100, avg QPS: 220, avg Response time: 241 ms
I've put the detail on google sheet:
