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.

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;
}

Updated lettuce redis client to latest snapshot, adopt changed API and use API for commands which were emulated using LUA script
Implemente Sentinel support using lettuce library, adopt finer grained exceptions and aligned exception behavior to match other libraries. Added shutdown-timeout property in order to control shutdown duration of the netty framework which reduces test run duration. Documentation updated as well. Contains also a fix to use psetex instead of setex (typo).
Switch to Jedis for Redis Version discovery in tests. Polished documentation. Use LettuceConverter and native time() method.

RedisTemplate now supports enabling of transaction support, which is disabled by default.
In case of enabled transaction support the RedisConnections will be bound to the current thread during ongoing outer transactions. We call MULTI at the beginning and depending on transaction state EXEC or DISCARD at its end.
To support read operations during the transaction we wrap a proxy around the bound connection piping read operations to a new (non thread bound) connection obtained by the underlying RedisConnectionFactory.
Transaction support is available for jedis, lettuce and srp, while had to be skipped for jredis due to the lack of support for MULTI.

'JRedisPool' and 'DefaultLettucePool' have been migrated to 'commons-pool2'.
'PoolConfig' has been deprecated, and will be removed in '1.4', as all required operations are available via 'GenericObjectPoolConfig'.
Along the way a minor bug within 'LettuceConnection' has been resolved, which prevented 'RedisAsyncConnections' from being properly closed/returned to pool.

Jedis upgraded from commons-pool to commons-pool2. Required changes have been introduced. Currently there are both commons-pool and commons-pool2 in class-path which is no problem as those dependencies are optional.
Original pull request: #31
Introduced Jackson2JsonRedisSerializer and added optional dependency for Jackson2 core/databind (fasterxml) library.
Added additional parameterised test cases. Needed to increase the max active connections limit for the connection pools used in RedisMapTests.
- Add DefaultJredisPool to pool JRedis connections
- Prevent returning the same resource to the pool
multiple times on JredisConnection close
- Fixes DATAREDIS-154 previous JRedis pool left
broken connections in the pool
