Getting Started with Redis Streams and Java

Redis Streams is a data type that represents a log, allowing new information and messages to be added in an append-only mode. It enables building "Kafka-like" applications with features like consumer groups for distributed message consumption, making it easy to scale and create highly available systems. Redis Streams differs from Redis Pub/Sub as they aim to accomplish different things. To learn how to use Redis Streams and Java, one can build a sample application using the redis-streams-101-java GitHub repository. The Lettuce Java client is recommended for working with Redis Streams. By creating a producer and consumer applications, messages can be posted to a stream, and consumed using a consumer group. This basic example demonstrates how to use Lettuce to publish messages to a stream, create a consumer group, and consume messages using the consumer group.
