RedisCache now expires keys using putIfAbsent if the key was set. Previously, the key was only expired if the value was already present and the value matched the value stored inside of Redis.
Original Pull Request: #224
We now allow usage of @GeoIndexed to mark GeoLocation or Point properties as candidates for secondary index creation. Non null values will be included in GEOADD command as follows:
GEOADD keyspace:property-path point.x point.y entity-id
@GeoIndexed can be used on top level as well as on nested properties.
class Person {
@Id String id;
String firstname, lastname;
Address hometown;
}
class Address {
String city, street, housenumber;
@GeoIndexed Point location;
}
The above allows us to derive geospatial queries from a given method using NEAR and WITHIN keywords like:
interface PersonRepository extends CrudRepository<Person, String> {
List<Person> findByAddressLocationNear(Point point, Distance distance);
List<Person> findByAddressLocationWithin(Circle circle);
}
Partial updates on the Point itself also trigger an index refresh operation. So it is possible to alter existing entities via:
template.save(new PartialUpdate<Person>("1", Person.class).set("address.location", new Point(17, 18));

We now make sure to count records without using criteria when derived criteria is empty. This allows usage of declared query methods using `Pageable` without criteria like `findBy(Pageable page)`.
Original Pull Request: #220
We now make sure to pipe finder queries without any criteria to the according find all method. This allows usage of `PagingAndSortingRepository.findAllBy(Pageable page)` as well as finders without any criteria like `findTop3By()`.

SCAN, SSCAN, HSCAN and ZSCAN now reference a dedicated connection that is bound to the Cursor. This allows creation of multiple cursors for different threads without the risk of potentially sharing a single connection. As before the caller is responsible for closing the Cursor correctly after usage.
Original pull request: #218.
We now unbind and release the connection from the transaction resources after a Redis command is invoked. Redis read operations return always null while using RedisTemplate in a transaction so Redis read transactions are not useful.
Previously, RedisConnection's were bound as transactional resource when used in the scope of a @Transactional(readOnly = true) method but not released on transaction completion. This was, because connections are not registered with a transaction synchronizer.

We now rely on getMissingCache and loadCaches for initialization instead of explicitly calling deprecated addCache method.

We now support Jedis 2.9.0 with Redis Standalone SSL and Redis Cluster with passwords. The code is compatible with Jedis 2.8.0 when not using SSL or Redis Cluster with passwords.
Original Pull Request: #211
Move duplicate code into single place and use ternary expressions where applicable.
Use static imports in tests where applicable.

Allow reading of the TTL into primitive properties. Allow general numeric types for TTL properties. Extend date range in license headers. Extend JavaDoc.
Original pull request: #208.
We now support ttl and pttl accepting a TimeUnit on connection level to return the TTL in the requested time unit. By performing the conversion inside the connection we return correct results for plain, pipelining and transaction execution. Add also JavaDoc and @Override to ttl/pttl methods.
Original pull request: #205.
getExpire returns now negative values without time unit conversion in case of absent values or values without a TTL set.

We now make sure to leave existing indexes untouched when using PartialUpdate.
We also fixed a glitch, where index values have not been removed correctly when saving entities with null values, along the way.
Original pull request: #207.
LettuceConnectionFactory and DefaultLettucePool now use the configured password to authenticate with Redis. Authentication is applied when connecting to nodes that were obtained from Redis Sentinel.

Extend date range in license header. Retrieve connection and config for possible reconfiguration only if keyspaceNotificationsConfigParameter has a value.
Original pull request: #202.
We now allow setting the desired notify-keyspace-events server configuration via @EnableRedisRepsoitories. Use `null` or an empty String for not touching the server’s config. The default is `Ex`.
Original pull request: #202.
RedisTemplate executePipelined(RedisCallback) uses now the Hash Key and Hash Value serializers to deserialize the response.

Update reference documentation. Enhance JavaDoc. Remove destroy of managed bean. Refactor property update of writePartialUpdate into own method. Remove trailing whitespaces in JavaDoc.
Original pull request: #191.
We now allow partial update of domain types via PartialUpdate. The according expiration times and secondary index structures are updated accordingly.
In some cases it is not necessary to load and rewrite the entire entity just to set a new value within it. A session timestamp for last active time might be such a scenario where you just want to alter one property.
`PartialUpdate` allows to define `set`, `delete` actions on existing objects while taking care of updating potential expiration times of the entity itself as well as index structures.
.Sample Partial Update
====
[source,java]
----
PartialUpdate<Person> update = new PartialUpdate<Person>("e2c7dcee", Person.class)
.set("firstname", "mat") <1>
.set("address.city", "emond's field") <2>
.del("age"); <3>
template.update(update);
update = new PartialUpdate<Person>("e2c7dcee", Person.class)
.set("address", new Address("caemlyn", "andor")) <4>
.set("attributes", singletonMap("eye-color", "grey")); <5>
template.update(update);
update = new PartialUpdate<Person>("e2c7dcee", Person.class)
.refreshTtl(true); <6>
.set("expiration", 1000);
template.update(update);
----
<1> Set the simple property _firstname_ to _mat_
<2> Set the simple property _address.city_ to _emond's field_ without having to pass in the entire object. This does not work when a custom conversion is registered.
<3> Remove the property _age_.
<4> Set complex property _address_.
<5> Set a map/collection of values removes the previously existing map/collection and replaces the values with the given ones.
<6> Automatically update the server expiration time when altering time to live.
====
NOTE: Updating complex objects as well as map/collection structures requires further interaction with Redis to determine existing values which means that it might turn out that rewriting the entire entity might be faster.

Set EnableRedisRepositories.enableKeyspaceEvents default to OFF. Expiry notifications require to opt-in. Add JavaDoc. Add documentation for delayed/disabled event listener. Fix spelling. Use property value instead of attribute on RedisKeyValueAdapter bean definition. Remove trailing white spaces.
Original pull request: #193.
We now allow more fine grained setup for usage of Redis keyspace events. This can be done programmatically via the RedisKeyValueAdapter or using `@EnableRedisRepositories.enableKeyspaceEvents`.
Original pull request: #193.
RedisGeoCommands now take and return Spring Data domain types like Distance and GeoResults.
Updated JavaDoc and Reference documentation.
Added and updated author and license headers.
Fixed minor formatting and code style issues.

We now throw DataRetrievalFailureException in case of get() when the underlying key storing the value of an AtomicInteger, AtomicLong or AtomicDouble is removed from Redis.

Added FasterXML Jackson `ObjectMapper` based `HashMapper` implementation that allows flattening.
```java
class Person {
String firstname;
String lastname;
Address address;
}
class Address {
String city;
String country;
}
```
```bash
firstname:Jon
lastname:Snow
address:{ city : Castle Black, country : The North }
firstname:Jon
lastname:Snow
address.city:Castle Black
address.country:The North
```

Do not destroy RedisConnectionFactory which is likely managed outside of RedisKeyValueAdapter.
This change makes sure to retain a working connection factory while shutting down message listeners as those try to unsubscribe on shutdown.

Rename ConvertingHashMapper to ObjectHashMapper. Add fromHash with type to avoid casting. Add JavaDoc documentation to HashMapper. Add hash mapping to reference documentation.
Original pull request: #194.
We now support mapping of simple and complex types to Redis HASH structures applying the same structure as the Repository support. This allows Object to hash Mapping and its direct usage via RedisTemplate without the need of explicitly having to use the repository abstraction.
Original pull request: #194.
We now pick up the ClassLoader from the ApplicationContext and use the latter as default in RedisTemplate for initializing the JdkSerializationRedisSerializer. We only do this in case the default serializer has not been set explicitly.
