An Argo Events deployment uses a NATS-based EventBus. The team observes that events received while the NATS pod was restarting are lost. Which change most effectively improves event durability?

Question

Accepted Answer

C. Switch the EventBus to use JetStream, which provides persistent message storage that survives pod restarts. Argo Events supports two EventBus backends: native NATS Streaming (limited persistence) and JetStream. JetStream provides persistent, replicated message storage so events published to the bus are not lost during NATS pod restarts or brief outages. Switching to a JetStream-backed EventBus is the documented approach for improving event durability. Increasing EventSource or Sensor replicas improves availability of those components but does not solve message loss at the EventBus transport layer.
