Redis pub/sub is ephemeral. Send to a topic and any active listeners will receive. If you need persistence then Redis v5 has a new data type called Streams which is similar to Kafka/Pulsar. Push messages to a stream and read with multiple consumers (using consumer groups) that can ack each msg to track read state.
