Thanks to all contributors who made Lettuce 5.1.0.M1 possible.
Lettuce 5.1.0.M1 requires Java 8, Java 9, or Java 10.

New Exceptions for Redis Responses

This release introduces new Exception types for the following Redis responses:

  • LOADING: RedisLoadingException
  • NOSCRIPT: RedisNoScriptException
  • BUSY: RedisBusyException

All exception types derive from RedisCommandExecutionException and do not require changes in application code.

Redis Streams (Preview)

Redis 5.0 is going to ship with support for a Stream data structure.
A stream is a log of events that can be consumed sequentially. A Stream message consists of an id and a body represented as hash (or Map<K, V>).

Lettuce provides access to Stream commands through RedisStreamCommands supporting synchronous, asynchronous, and reactive execution models. All Stream commands are prefixed with X (XADD, XREAD, XRANGE).

Stream messages are required to be polled. Polling can return either in a non-blocking way without a message if no message is available, or, in a blocking way. XREAD allows to specify a blocking duration in which the connection is blocked until either the timeout is exceeded or a Stream message arrives.

The following example shows how to append and read messages from a Redis Stream:

// Append a message to the stream
String messageId = redis.xadd("my-stream", Collections.singletonMap("key", "value"));

// Read a message
List<StreamMessage<String, String>> messages = redis.xread(StreamOffset.from("my-stream", messageId));


redis.xadd("my-stream", Collections.singletonMap("key", "value"));

// Blocking read
List<StreamMessage<String, String>> messages = redis.xread(XReadArgs.Builder.block(Duration.ofSeconds(2)), 
                                                           StreamOffset.latest("my-stream"));

Redis Streams support the notion of consumer groups. A consumer group is a group of one or more consumers that tracks the last consumed Stream message and allows explicit acknowledgment of consumed messages.

// Setup stream, see https://github.com/antirez/redis/issues/4824
redis.xadd("my-stream", Collections.singletonMap("key", "value"));

// Create consumer group
redis.xgroupCreate("my-stream", "my-group", "$");
redis.xadd("my-stream", Collections.singletonMap("key", "value"));

// Read stream messages in the context of a consumer
List<StreamMessage<String, String>> messages = redis.xreadgroup(Consumer.from("my-stream", "consumer1"),
                XReadArgs.Builder.noack(),
                StreamOffset.lastConsumed(key));

// process message

…

// Acknowledge message
redis.xack(key, "group", messages.get(0).getId());

Please note that the Redis Stream implementation is not final yet and the API is subject to change if the Redis API changes.

Scan Stream

Lettuce 5.1 ships with a reactive SCAN stream API that allows reactive and demand-aware usage of Redis' SCAN commands. SCAN is an interator-based command that requires multiple round-trips to Redis to scan the keyspace or a particular data structure. Instead of calling SCAN from your application code, you can use ScanStream as entrypoint to SCAN, HSCAN, SSCAN, and ZSCAN operations.
ScanStream returns a Flux that can be consumed as a single stream without the need of continuing the actual iteration. That's covered by Lettuce for you.

The LIMIT argument controls the batchsize. Demand (backpressure) is translated into cursor call. If you stop consuming the stream, no further SCAN calls are issued.

RedisReactiveCommands<String, String> reactive = redis.getStatefulConnection().reactive();

Flux<String> keys = ScanStream.scan(reactive, ScanArgs.Builder.limit(200));

Asynchronous non-blocking Connection Pooling

Right now, applications that utilize connection pooling in combination with a non-blocking API (asynchronous or reactive API users) are limited to Apache Commons Pool which is a blocking object pool implementation.

This release ships with non-blocking pooling support through AsyncPool that is obtained from AsyncConnectionPoolSupport. The pooling API allows for various implementations. As of Lettuce 5.1, a bounded pool is provided that allows limiting and that signals pool exhaustion by emitting NoSuchElementException.

The pooling API returns CompletableFuture instances to synchronize acquire and release operations. AsyncPool does not require external dependencies and features an improved performance profile in comparison to Apache Commons Pool 2.
This non-blocking pooling API is not a replacement for the blocking pool although it's possible that may provide a blocking layer that exports the pooling functionality through org.apache.commons.pool2.ObjectPool.

The following example show how to use AsyncPool.

AsyncPool<StatefulRedisConnection<String, String>> pool = AsyncConnectionPoolSupport.createBoundedObjectPool(
        () -> client.connectAsync(StringCodec.UTF8, uri),
        BoundedPoolConfig.builder()
                    .minIdle(4)
                    .maxIdle(8)
                    .maxTotal(16)
                    .testOnAcquire()
                    .build());

// Acquire connection and do some work
CompletableFuture<StatefulRedisConnection<String, String>> acquire = pool.acquire();

acquire.thenAccept(connection -> {

    connection.async().set("key", "value").whenComplete((v, e) -> {
        pool.release(connection);
    });
});


// later
CompletableFuture<Void> closeFuture = pool.closeAsync();

Global Command Timeouts

Lettuce can be used through various APIs. The most common one is the synchronous API which emulates blocking behavior on top of a reactive and non-blocking driver. A natural aspect of blocking APIs are timeouts
when it comes to I/O. Using the asynchronous or reactive API do not have timeouts as there was no active component that tracked command runtime durations.

With Lettuce 5.1, you get the possibility to configure a global command timeout through ClientOptions and TimeoutOptions that can determine timeouts on a RedisCommand basis. This timeout applies on a command basis and completes commands with RedisCommandTimeoutException.

You can change the timeout on running connections through RedisURI.setTimeout(…), RedisClient.setDefaultTimeout(…), and StatefulConnection.setTimeout(…) if TimeoutOptions are enabled - global command timeouts are disabled by default.

TimeoutOptions timeoutOptions = TimeoutOptions.enabled(Duration.ofMinutes(1));

ClientOptions.builder().timeoutOptions(timeoutOptions).build();

Thanks to all contributors that made Lettuce 5.1.0.M1 possible.

Lettuce 5.1.0.M1 requires Java 8 and cannot be used with Java 6 or 7.
