Answer» The following table ILLUSTRATES the DIFFERENCES between Redis and Kafka: | Redis | Kafka |
|---|
| Push-based message delivery is supported by Redis. This means that messages published to Redis will be distributed to consumers automatically. | Pull-based message delivery is supported by Kafka. The messages published to the Kafka broker are not automatically sent to the consumers; instead, consumers must pull the messages when they are ready. | | Message retention is not supported by Redis. The communications are DESTROYED once they have been delivered to the recipients. | In its LOG, Kafka allows for message preservation. | | Parallel processing is not supported by Redis. | Multiple consumers in a consumer group can consume partitions of the topic concurrently because of the Kafka's partitioning feature. | | Redis can not MANAGE vast amounts of data because it's an in-memory database. | Kafka can handle massive amounts of data since it uses disc space as its primary storage. | | Because Redis is an in-memory store, it is much faster than Kafka. | Because Kafka stores data on disc, it is slower than Redis. |
