We now allow constructing JdkSerializationRedisSerializer using an own class loader and by specifying custom converters.
Using an own class-loader: new JdkSerializationRedisSerializer(classLoader)
Using own converters (Serializer/Deserializer): new JdkSerializationRedisSerializer(new SerializingConverter(), new DeserializingConverter(new DefaultDeserializer(classLoader)))

We now preserve the item order when converting list elements. This does not mean that we place elements at the exact position retrieved from the store but rather maintain their order based on the index value.
Additionally applied some documentation polishing and cluster tests.
Original Pull Request: #156
We ship converters for JSR-310 types (LocalDate/Time, ZonedDateTime, Period, Duration and ZoneId) to map between UTF-8-encoded byte[] and JDK 8 date/time types.
We also export Redis Repositories in a CDI environment. Repositories can be injected using @Inject. The CDI extension requires at least RedisOperations to be provided. Other beans like RedisKeyValueAdapter and RedisKeyValueTemplate can be provided by the user. If no RedisKeyValueAdapter/RedisKeyValueTemplate beans are found, the CDI extension creates own managed instances.

- Add a composite IndexResolver implementation that iterates over a given collection of delegate IndexResolver instances and collects IndexedData from those.
- Break up cycle involving ReferenceResolver and let the resolver just returns the raw hash.
- Remove IndexType and use dedicated classes for index definitions.
- Fix pagination error and follow up to changes introduced via DATAKV-123.
Original Pull Request: #156
This commit adds support for distinguishing between
the property path that is being indexed and the
name of the index that should be used.
This is useful when you do not want the property
path and index name to be the same. For example,
if you want to use Spel expressions, it may not be
possible to use the path as the name of the index.
Original PR #160
We now enable storing domain object as a flat Redis 'HASH' and maintain additional 'SET' structures to enable finder operations on simple properties.
@RedisHash("persons");
class Person {
@id String id;
@Indexed String firstname;
String lastname;
Map<String, String> attributes;
City city;
@Reference Person mother;
}
The above is stored in the HASH with key 'persons:1' as
_class = org.example.Person
id = 1
firstname = rand
lastname = al’thor
attributes.[eye-color] = grey
attributes.[hair-color] = red
city.name = emond's field
city.region = two rivers
mother = persons:2
Complex types are flattened out to their full property path for each of the values provided. If the properties actual value type does not match the declared one the '_class' type hint is added to the entry.
city._class = CityInAndor.class
city.name = emond's field
city.region = two rivers
city.country = andor
Map and Collection like structures are stored with their key/index values as part of the property path. If the map/collection value type does not match the actutal objects one the '_class' type hint is added to the entry.
list.[0]._class = DomainType.class
list.[0].property1 = ...
map.[key-1]._class = DomainType.class
map.[key-1].property1 = ...
Properties marked with '@Reference' are stored as semantic references by just storing the key to the referenced object 'HASH' instead of embedding its values.
mother = persons:2
Please note that referenced objects are not transitively updated/saved and that lazy loading of references will be part of future development.
A 'save' operation therefore executes the following:
# flatten domain type and add as hash
HMSET persons:1 id 1 firstname rand …
# add the newly inserted entry to the list of all entries of that type
SADD persons 1
# index the firstname for finder lookup
SADD persons.firstname:rand 1
Simple finder operation like 'findByFirstname' use 'SINTER' to find matching
SINTER persons.firstname:rand
HGETALL persons:1
Besides resolving an index via the '@Index' annotation we also allow to add custom configuration via the 'indexConfiguration' attribute of '@EnableRedisRepositories'.
@Configuration
@EnableRedisRepositories(indexConfiguration = CustomIndexConfiguration.class)
class Config { }
static class CustomIndexConfiguration extends IndexConfiguration {
@Override
protected Iterable<RedisIndexDefinition> initialConfiguration() {
return Arrays.asList(
new SimpleIndexDefinition("persons", "lastname"),
);
}
}
The '@TimeToLive' annotation allows to define a property or method providing an expiration time when storing the key in redis.
@RedisHash
class Person {
@Id String id;
@TimeToLive Long ttl;
}

Add DecoratedRedisConnection interface to unwrap decorated connections. When running on Redis Cluster, use keys/del instead of lua script because cluster connections do not support lua script execution.
Original pull request: #173.
We now guard multi/exec blocks by checking the connection type. This allows to skip those commands when running in cluster.
Original pull request: #173.
We moved away from returning raw map types and now return dedicated objects for command executions in cluster environment. This allows to maintain node information and collecting results from each and every callback. MGET now returns values according to the key position.
Additionally we now prefix info commands in the cluster with the nodes host:port.

Add ClientResources to LettuceConnectionFactory. Add TestClientResources for managed resources during tests and reuse ClientResources as much as possible in tests.

We now support EX/PX and NX/XX arguments along with the SET command for both xetorthio/jedis and mp911de/lettuce.
Jedis 2.8 does not support all combinations of EX/PX and NX/XX. To work around those limitations we delegate to the according set methods to execute related commands or fail fast if there is no way for delegation.

Add new config property to configure a password for operations with Redis Cluster. The only driver to support Redis Cluster with password is lettuce but 3.4.Final has a blocker bug that prevents the usage

Update documentation and fix spelling in JavaDoc and reference documentation.
Allow node lookup by host/port and node Id to enable flexibility when passing references to Redis Cluster nodes. Parse multiple slot ranges for a cluster node and move CLUSTER NODES parser to Converters.
Use fixed line separator instead of OS-specific line separator, consolidate duplicate code, support clusterSetSlotStable with lettuce 3.4 and set lettuce driver shutdown timeout to zero for long running tests.
Original pull request: #158.
Cluster support is based on the very same building blocks as non clustered communication. RedisClusterConnection and extension to RedisConnection handles the communication with the Redis Cluster and translates errors into the Spring DAO exception hierarchy.
Redirects for to a specific keys to the corresponding slot serving node are handled by the driver libraries, higher level functions like collecting information accross nodes, or sending commands to all nodes in the cluster that are covered by RedisClusterConnection utilizing a ClusterCommandExecutor distributing commands accross the cluster and collecting results.
RedisTemplate provides access to cluster specific operations via the ClusterOperations interface that can be obtained via RedisTemplate.opsForCluster(). This allows to execute commands explicitly on a single node within the cluster while retaining de-/serialization features configured for the template.

As of Spring Framework 4.3.RC1, the `Cache` interface has a new `<T> T get(Object key, Callable<T> valueLoader);` method (see SPR-9254).
If no entry for the given key is found, the `Callable` is invoked to compute/load the value that is then put into redis and returned. Additionally concurrent calls get synchronized so that the `Callable` is only called once.
Using Spring Framework 4.3 failures result in `o.s.c.Cache$ValueRetrievalException` prior versions use `RedisSystemException`.
