I protype with moleculer and just wondering on an architecural issue. My app is build with many pieces: moleculer services, redis, nats, C language app,... and it's deployed on ks8 cluster. I have to subscribe to an event published by moleculer service in my C app. Having redis and nats on board I have to options:

  • use native ioredis api from moleculer servise to publish an event and consume it in my C client (done)
  • use NATS moleculer tansporter and consume it in C client (not even started)

What is suggested way of dealing with such architecture from your point of view?

If measured by performance, then NATS will outperform REDIS on large data volumes.

If it’s a matter of architecture design, then you won’t be able to take some moleculer events, you will need to fully implement the broker protocol and process events already. I do not think that this option is suitable for you. It is better to use a separate data bus, and in moelculer to make a service that will transmit internal events to the external data bus.
