+# Spring Data Redis - Streams Examples
+
+The [Redis Stream](https://redis.io/topics/streams-intro) is a new data type introduced with Redis 5.0 modelling log data structure.
+Spring Data Redis supports _Redis Streams_ via both the imperative and the reactive API.
+
+## Imperative API
+
+**Basic Usage**
+```java
+@Autowired 
+RedisTemplate template;
+
+StringRecord record = StreamRecords.string(…)
+    .withStreamKey("my-stream");
+RecordId id = template.streamOps().add(record);
+
+List<...> records = template.streamOps().read(count(2), from(id));
+```
+
+**ContinuousRead Read**
+```java
+@Autowired 
+RedisConnectionFactory factory;
+
+StreamListener<String, MapRecord<…> listener = 
+  (msg) -> {
+    // ...
+  };
+
+StreamMessageListenerContainer container = StreamMessageListenerContainer.create(factory));
+
+container.receive(StreamOffset.fromStart("my-stream"), listener);
+```
+
+## Reactive API
+
+**Basic Usage**
+```java
+@Autowired 
+ReactiveRedisTemplate template;
+
+StringRecord record = StreamRecords.string(…)
+    .withStreamKey("my-stream");
+Mono<RecordId> id = template.streamOps().add(record);
+
+Flux<...> records = template.streamOps().read(count(2), from(id));
+```
+
+**ContinuousRead Read**
+```java
+@Autowired 
+ReactiveRedisConnectionFactory factory;
+
+StreamReceiver receiver = StreamReceiver.create(factory));
+
+container.receive(StreamOffset.fromStart("my-stream"))
+    .doOnNext((msg) -> {
+    	// ...
+    })
+    .subscribe();
+```
