= Spring Data KeyValue image:https://img.shields.io/badge/Revved%20up%20by-Develocity-06A0CE?logo=Gradle&labelColor=02303A["Revved up by Develocity", link="https://ge.spring.io/scans?search.rootProjectNames=Spring Data KeyValue"]

The primary goal of the https://projects.spring.io/spring-data[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.

This module provides infrastructure components to build repository abstractions for stores dealing with Key/Value pairs and ships with a default `java.util.Map` based implementation.

== Features

* Infrastructure for building repositories on top of key/value implementations.

* Dynamic SpEL query generation from query method names.

* Possibility to integrate custom repository code.

== Getting Started

Here is a quick teaser of an application using Spring Data Repositories in Java:

[source,java]

----

public interface PersonRepository extends CrudRepository {

    List findByLastname(String lastname);

    List findByFirstnameLike(String firstname);

}

@Service

public class MyService {

    private final PersonRepository repository;

    public MyService(PersonRepository repository) {

        this.repository = repository;

    }

    public void doWork() {

        repository.deleteAll();

        Person person = new Person();

        person.setFirstname("Oliver");

        person.setLastname("Gierke");

        repository.save(person);

        List lastNameResults = repository.findByLastname("Gierke");

        List firstNameResults = repository.findByFirstnameLike("Oli*");

    }

}

@KeySpace("person")

class Person {

    @Id String uuid;

    String firstname;

    String lastname;

    // getters and setters omitted for brevity

}

@Configuration

@EnableMapRepositories("com.acme.repositories")

class AppConfig { … }
