Spring Data for Apache Cassandra offers a familiar interface to those who have used other Spring Data modules in the past.\n\nThe learning curve for developing applications with Apache Cassandra is significantly reduced when using Spring Data for Apache Cassandra.\nWith the power to stay at a high level with annotated POJOs, or at a low level with high performance data ingestion capabilities, the Spring Data for Apache Cassandra templates are sure to meet every application need.\n\n== Features\n\n* Build repositories based on common Spring Data interfaces\n* Support for synchronous, reactive, and asynchronous data operations\n* Support for XML based Keyspace creation and CQL Table creation\n* JavaConfig and XML Support for all Cluster and Session Capabilities\n* Exception Translation to the familiar Spring DataAccessException hierarchy\n* Convenient QueryBuilders to eliminate the need to learn CQL\n* Automatic implementation of Repository interfaces including support for custom query methods\n* Based on the 4.x DataStax CQL Java Driver\n\n== Code of Conduct\n\nThis project is governed by the https://github.com/spring-projects/.github/blob/e3cc2ff230d8f1dca06535aa6b5a4a23815861d4/CODE_OF_CONDUCT.md[Spring Code of Conduct]. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.\n\n== Getting Started\n\nHere is a quick teaser of an application using Spring Data Repositories in Java:\n\n[source,java]\n----\npublic interface PersonRepository extends CrudRepository\u003cPerson, Long\u003e {\n\n  List\u003cPerson\u003e findByLastname(String lastname);\n\n  List\u003cPerson\u003e findByFirstnameLike(String firstname);\n}\n\n@Service\npublic class MyService {\n\n  private final PersonRepository repository;\n\n  public MyService(PersonRepository repository) {\n    this.repository = repository;\n  }\n\n  public void doWork() {\n\n    repository.deleteAll();\n\n    Person person = new Person();\n    person.setFirstname(\"Matthew\");\n    person.setLastname(\"Adams\");\n    repository.save(person);\n\n    List\u003cPerson\u003e lastNameResults = repository.findByLastname(\"Adams\");\n    List\u003cPerson\u003e firstNameResults = repository.findByFirstnameLike(\"M*\");\n }\n}\n\n@Configuration\n@EnableCassandraRepositories\nclass ApplicationConfig extends AbstractCassandraConfiguration {\n\n  @Override\n  public String getContactPoints() {\n    return \"localhost\";\n  }\n\n  @Override\n  protected String getKeyspaceName() {\n    return \"springdata\";\n  }\n}\n----\n\n=== Maven configuration\n\nAdd the Maven dependency:\n\n[source,xml]\n----\n\u003cdependency\u003e\n  \u003cgroupId\u003eorg.springframework.data\u003c/groupId\u003e\n  \u003cartifactId\u003espring-data-cassandra\u003c/artifactId\u003e\n  \u003cversion\u003e${version}\u003c/version\u003e\n\u003c/dependency\u003e\n----\n\nIf you'd rather like the latest snapshots of the upcoming major version, use our Maven snapshot repository and declare the appropriate dependency version.\n\n[source,xml]\n----\n\u003cdependency\u003e\n  \u003cgroupId\u003eorg.springframework.data\u003c/groupId\u003e\n  \u003cartifactId\u003espring-data-cassandra\u003c/artifactId\u003e\n  \u003cversion\u003e${version}-SNAPSHOT\u003c/version\u003e\n\u003c/dependency\u003e\n\n\u003crepository\u003e\n  \u003cid\u003espring-snapshot\u003c/id\u003e\n  \u003cname\u003eSpring Snapshot Repository\u003c/name\u003e\n  \u003curl\u003ehttps://repo.spring.io/snapshot\u003c/url\u003e\n\u003c/repository\u003e\n----\n\n== Getting Help\n\nHaving trouble with Spring Data? We’d love to help!\n\n* Check the\nhttps://docs.spring.io/spring-data/cassandra/docs/current/reference/html/[reference documentation], and https://docs.spring.io/spring-data/cassandra/docs/current/api/[Javadocs].\n* Learn the Spring basics – Spring Data builds on Spring Framework, check the https://spring.io[spring.io] web-site for a wealth of reference documentation.\nIf you are just starting out with Spring, try one of the https://spring.io/guides[guides].\n* Ask a question - we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-data[`spring-data-cassandra`].\n* Report bugs with Spring Data for Apache Cassandra at https://github.com/spring-projects/spring-data-cassandra/issues[github.com/spring-projects/spring-data-cassandra/issues].\n\n== Reporting Issues\n\nSpring Data uses GitHub as issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:\n\n* Before you log a bug, please search the\nhttps://github.com/spring-projects/spring-data-cassandra/issues[issue tracker] to see if someone has already reported the problem.\n* If the issue does not already exist, https://github.com/spring-projects/spring-data-cassandra/issues/new[create a new issue].\n* Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using and JVM version.\n* If you need to paste code, or include a stack trace use Markdown +++```+++ escapes before and after your text.\n* If possible try to create a test-case or project that replicates the issue. Attach a link to your code or a compressed file containing your code.\n\n== Building from Source\n\nYou don’t need to build from source to use Spring Data (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper].\nYou also need JDK 17.\n\n[source,bash]\n----\n $ ./mvnw clean install\n----\n\nIf you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.8.0 or above].\n\n_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular please sign the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change._\n\n== Initial Contributors\n\nSpring Data for Apache Cassandra was initially created and supported by the following companies and individuals:\n\n* http://www.prowaveconsulting.com[Prowave Consulting] - David Webb\n* http://www.scispike.com[SciSpike] - Matthew Adams\n* John McPeek\n\n=== Building reference documentation\n\nBuilding the documentation builds also the project without running tests.\n\n[source,bash]\n----\n $ ./mvnw clean install -Pantora\n----\n\nThe generated documentation is available from `spring-data-cassandra-distribution/antora/site/index.html`.\n\n== Examples\n\n* https://github.com/spring-projects/spring-data-examples/[Spring Data Examples] contains example projects that explain specific features in more detail.\n\n== License\n\nSpring Data for Apache Cassandra is Open Source software released under the https://www.apache.org/licenses/LICENSE-2.0.html[Apache 2.0 license].\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fspring-projects%2Fspring-data-cassandra","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fspring-projects%2Fspring-data-cassandra","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fspring-projects%2Fspring-data-cassandra/lists"}
