Is it safe to run Redis without persistence?

As we are running chirpstack in kubernets environment and try to minimize peristence (to be as stateless as we can be), the question came up if we just can run redis without persistence.

From reading docs I would say yes as chirpstack AS and NS only store non persistent (runtime?) data in redis.

I would advise no.

OK clear answer.

@brocaar would be nice to clarify this in docs though: Requirements - ChirpStack open-source LoRaWAN<sup>®</sup> Network Server
