Spring Data Aerospike

The primary goal of the Spring Data project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.

The Spring Data Aerospike project aims to provide a familiar and consistent Spring-based programming model for new datastores while retaining store-specific features and capabilities. The Spring Data Aerospike project provides integration with the Aerospike document database. Key functional areas of Spring Data Aerospike are a POJO centric model for interacting with a Aerospike DBCollection and easily writing a repository style data access layer.

Spring Boot compatibility

spring-data-aerospike Version	Spring Boot Version
2.4.2.RELEASE	2.3.x
2.3.5.RELEASE	2.2.x
2.1.1.RELEASE	2.1.x, 2.0.x
1.2.1.RELEASE	1.5.x

Quick Start

Maven configuration

Add the Maven dependency:

<dependency>
  <groupId>com.aerospike</groupId>
  <artifactId>spring-data-aerospike</artifactId>
  <version>2.4.2.RELEASE</version>
</dependency>

The Aerospike Spring Data connector depends on the Aerospike Client project:

<dependency>
  <groupId>com.aerospike</groupId>
  <artifactId>aerospike-client</artifactId>
</dependency>

Dependency will be provided for you by spring-data-aerospike, so no need to declare it additionally.

AerospikeTemplate

AerospikeTemplate is the central support class for Aerospike database operations. It provides:

• Basic POJO mapping support to and from Bins
• Convenience methods to interact with the store (insert object, update objects) and Aerospike specific ones.
• Connection affinity callback
• Exception translation into Spring's technology agnostic DAO exception hierarchy.

Spring Data repositories

To simplify the creation of data repositories Spring Data Aerospike provides a generic repository programming model. It will automatically create a repository proxy for you that adds implementations of finder methods you specify on an interface.

For example, given a Person class with first and last name properties, a PersonRepository interface that can query for Person by last name and when the first name matches a like expression is shown below:

public interface PersonRepository extends CrudRepository<Person, Long> {

  List<Person> findByLastname(String lastname);

  List<Person> findByFirstnameLike(String firstname);
}

The queries issued on execution will be derived from the method name. Extending CrudRepository causes CRUD methods being pulled into the interface so that you can easily save and find single entities and collections of them.

You can have Spring automatically create a proxy for the interface by using the following JavaConfig:

@Configuration
@EnableAerospikeRepositories(basePackageClasses = PersonRepository.class)
class ApplicationConfig extends AbstractAerospikeDataConfiguration {
	
	@Override
    protected Collection<Host> getHosts() {
    	return Collections.singleton(new Host("localhost", 3000));
    }
    
    @Override
    protected String nameSpace() {
    	return "TEST";
    }
	
}

This sets up a connection to a local Aerospike instance and enables the detection of Spring Data repositories (through @EnableAerospikeRepositories).

This will find the repository interface and register a proxy object in the container. You can use it as shown below:

@Service
public class MyService {

  private final PersonRepository repository;

  @Autowired
  public MyService(PersonRepository repository) {
    this.repository = repository;
  }

  public void doWork() {

     repository.deleteAll();

     Person person = new Person();
     person.setFirstname("Oliver");
     person.setLastname("Gierke");
     person = repository.save(person);

     List<Person> lastNameResults = repository.findByLastname("Gierke");
     List<Person> firstNameResults = repository.findByFirstnameLike("Oli*");
 }
}
