Interface CassandraRepository<T,ID>

All Superinterfaces:

CrudRepository<T,ID>, Repository<T,ID>

All Known Subinterfaces:

MapIdCassandraRepository<T>

All Known Implementing Classes:

SimpleCassandraRepository

@NoRepositoryBean
public interface CassandraRepository<T,ID>
extends CrudRepository<T,ID>

Cassandra-specific extension of the CrudRepository interface that allows the specification of a type for the identity of the @Table (or @Persistable) type.

Repositories based on CassandraRepository can define either a single primary key, use a primary key class or a compound primary key without a primary key class. Types using a compound primary key without a primary key class must use MapId to declare their key value.

Method Summary

Modifier and Type	Method and Description
List<T>	findAll()
Slice<T>	findAll(Pageable pageable) Returns a Slice of entities meeting the paging restriction provided in the Pageable object.
List<T>	findAllById(Iterable<ID> ids) Note: Cassandra supports single-field IN queries only.
<S extends T> List<S>	insert(Iterable<S> entities) Inserts the given entities.
<S extends T> S	insert(S entity) Inserts the given entity.

Method Detail

saveAll

<S extends T> List<S> saveAll(Iterable<S> entites)

Specified by:

saveAll in interface CrudRepository<T,ID>

findAll

List<T> findAll()

Specified by:

findAll in interface CrudRepository<T,ID>

findAllById

List<T> findAllById(Iterable<ID> ids)

Note: Cassandra supports single-field IN queries only. When using MapId with multiple components, use CrudRepository.findById(Object).

Specified by:

findAllById in interface CrudRepository<T,ID>

Throws:

InvalidDataAccessApiUsageException - thrown when using MapId with multiple key components.

findAll

Slice<T> findAll(Pageable pageable)

Returns a Slice of entities meeting the paging restriction provided in the Pageable object.

Parameters:

pageable - must not be null.

Returns:

a Slice of entities.

Since:

2.0

insert

<S extends T> S insert(S entity)

Inserts the given entity. Assumes the instance to be new to be able to apply insertion optimizations. Use the returned instance for further operations as the save operation might have changed the entity instance completely. Prefer using CrudRepository.save(Object) instead to avoid the usage of store-specific API.

Parameters:

entity - must not be null.

Returns:

the saved entity

Since:

2.0

insert

<S extends T> List<S> insert(Iterable<S> entities)

Inserts the given entities. Assumes the given entities to have not been persisted yet and thus will optimize the insert over a call to saveAll(Iterable). Prefer using saveAll(Iterable) to avoid the usage of store specific API.

Parameters:

entities - must not be null.

Returns:

the saved entities

Since:
