We now provide a more fine-grained exception translation for exceptions that previously mapped to CassandraUncategorizedException. Existing translation to more specific exception does not change. The following translation rules are introduced by this change:
* OverloadedException and BootstrappingException map to TransientDataAccessResourceException
* NoHostAvailableException, BusyPoolException, ConnectionException, BusyConnectionException map to CassandraConnectionFailureException
* QueryConsistencyException, FunctionExecutionException map to DataAccessResourceFailureException
Align declared type of CassandraCqlTemplateFactoryBean to CqlTemplate and the type of CassandraTemplateFactoryBean to CassandraTemplate to report consistent bean types. Add JavaDoc.

Reuse Thread pools during integration test runs to not recreate and dispose Threads multiple times. Increase build and Cassandra memory. Use an external Cassandra instance for TravisCI build jobs.
Revert added features in version 1.0 schema files in favor of version 1.5 schema files. Remove license header. Remove TODOs and fix documentation source names.
We now support Cassandra User-defined types. UDTs can be created using CQL generators and used inside of mapped domain classes. User-defined types can be used either raw as UDTValue that is passed through or as mapped object. Mapped UDTs must be annotated with @UserDefinedType. Types are included into schema generation so known and defined UDTs are created before any tables are created. UDTs can be used with set and list collection types and in primary keys. UDTs can also be used in repository query methods as query predicates.
Updating UDTs will update the whole UDT.
@UserDefinedType
public class Address {
String city;
String country;
}
@Table
public class Person {
@Id String id;
Address address;
UDTValue genericUdt;
}
The XML namespace support was extended with new schema versions to support provide a User Type resolver so UDTs can be resolved:
<cassandra:mapping>
<cassandra:user-type-resolver keyspace-name="${cassandra.keyspace}" />
</cassandra:mapping>
We now rely on Row.getObject(…) to retrieve data from a Cassandra Column. CodecRegistry and ProtocolVersion are configured on Cluster so there's no need to use a static configured CodecRegistry and ProtocolVersion that might not fit the configured values.
High client churn seems to affect Cassandra in a negative way (connection timeouts, driver considers hosts as down). Almost all integration tests bootstrap their own Cluster instance and dispose it once the tests has finished. Identify tests where reuse of a global Cluster instance provided by CassandraRule is possible and switch from context bootstrapping to reuse. This helps to prevent integration test failures.
We now support `NettyOptions` bean references in XML-based configuration.
<bean id="nettyOptions" class="…" />
<cass:cluster contact-points="…" netty-options-ref="nettyOptions" />
Switch heartbeatIntervalSeconds, idleTimeoutSeconds and poolTimeoutMilliseconds to primitive integers and compare values against defaults to decide whether to set these properties on PoolingOptions.
We are now compatible with Datastax’ Cassandra Driver 3.1.1 and support the newly introduced configuration options MaxQueueSize for PoolingOptions.
This change also removes test assertions for PoolTimeoutMillis as this option was deprecated and made unusable with 3.1.1.
Deprecate our org.springframework.cassandra.core.ConsistencyLevel enum. Having an own consistency level type leads to confusion and it's always behind the driver. We don't want to maintain that type, so we decided to deprecate the own type and use the driver consistency levels.
We allow now the use of the driver retry policies aside of our consistency level enumeration. For most cases, our enumeration is the simpler approach. Some retry policies (IdempotenceAwareRetryPolicy, LoggingRetryPolicies) require further configuration and cannot be applied with just using a static enum value. We now support ReadTimeout, FetchSize, and Tracing via QueryOptions and WriteOptions and provide builders for QueryOptions and WriteOptions.

Add author tags. Extend date range in headers. Simplify resolution by removing intermediate variables. Add test to verify ConsistencyLevel resolution. Guard consistency level against null.

We allow users to provide a ClusterBuilderConfigurer that can be applied to the Cluster Builder. ClusterBuilderConfigurer is a callback interface to handle extended configuration when the DataStax API changes. It allows configuration of options after all provided properties were set.

We now support configuration of the cluster name, AddressTranslator, MaxSchemaAgreementWaitSeconds, SpeculativeExecutionPolicy and TimestampGenerator in the Cassandra Cluster factory. The cluster name is derived from the bean name, if not configured otherwise.

We now check first whether any CQL statements need to be executed. This makes the code simpler because we don't have to check whether the session has already been created. Rename the Session variable system to session to omit confusion. Remove CQL logging here as CQL statements are logged inside the CqlTemplate.

Extend alter table specification and the linked CQL generator to support RENAME and DROP operations. Cleanup code in that area.

Extends date range in license headers. Apply formatting rules. Create BeanDefinitionTestUtils and simplify tests. Add ticket references.

We now support java.util.stream.Stream as return type on query methods. Streaming queries wrap the iterator returned by Cassandra's ResultSet. Elements are fetched in batches (see QueryOptions that can be set in CassandraCqlClusterFactoryBean) and processed element by element instead of reading all results. Streaming queries are supported only for select queries.
