Using NoSQL with JPA, CDI and Java EE

Publié le

This session explores how NoSQL solutions like MongoDB, Cassandra, Neo4j, HBase and CouchDB can be used in a Java EE application with or without a JPA facade. Although the primary focus is on EclipseLink NoSQL, we will also cover Hibernate OGM, EasyCassandra, Morphia, etc as well as seeing how NoSQL can be used natively via basic CDI injection.

  4. 4. NoSQL Landscape • Non-conformance to established RDMS paradigm • No SQL/queries, no schemas, weak referential integrity, no JOINs • Scalability and cost major motivators • ACID vs. BASE • Unstructured data minor motivator • Mostly complement and not replace relational databases • Extremely divergent, specialized products • Some taxonomies • Key/value, document, graph, etc • MongoDB, Cassandra, Google BigTable, CouchDB, HBase, Redis, Neo4j Copyright © 2015 CapTech Ventures, Inc. All rights reserved. Wild, Wild West
  5. 5. NoSQL Landscape Copyright © 2015 CapTech Ventures, Inc. All rights reserved. Adoption and Trends
  6. 6. The Case for JPA • There almost always is a domain model • Most of JPA fits NoSQL quite well • Learning each diverging NoSQL product cumbersome, often unnecessary • Switching between NoSQL solutions difficult • “Polyglot Persistence” difficult • NoSQL APIs generally low level, verbose Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  7. 7. Applying JPA to NoSQL • JPA domain model concepts apply well to NoSQL • Entities, Embeddables, OneToOne, OneToMany, ManyToOne, ManyToMany • Pure relational concepts may not apply well • Table, Column, JoinTable, JoinColumn • JPA queries can fit relatively well • Basic finders (by identity, all) • JPQL—portable query language defined by the spec • Native query—lets you leverage database specific features Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  8. 8. EclipseLink NoSQL • Support JPA style access to NoSQL databases • Leverage existing non-relational database support • Metadata to identify NoSQL entities (e.g. @NoSQL) • Support JPQL subset • Leverage what’s available • Initial support for MongoDB and Oracle NoSQL • More to come (Cassandra, HBase, CouchDB?) • Support mixing relational and non-relational data in single composite persistence unit (“polyglot persistence”) Copyright © 2015 CapTech Ventures, Inc. All rights reserved.

  10. 10. Other JPA/NoSQL Solutions • Hibernate OGM • Utilizes Hibernate codebase for NoSQL • MongoDB, Cassandra, Neo4J, CouchDB, Infinispan, Ehcache • Tries to provide as much of JPA as possible, including queries via Hibernate Search/Lucene, relational mapping annotations • DataNucleus • Persistence layer behind Google App Engine • MongoDB, Cassandra, HBase, Neo4J • Kundera • Cassandra, MongoDB, HBase, Redis, Neo4J, Oracle NoSQL, CouchDB Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  11. 11. CDI Overview • Next-generation dependency injection for Java EE • Synthesizes best ideas from Seam 2, Guice and Spring • Many innovative features on its own right • Focus on loose-coupling, Java-centric type-safety, annotations, expressiveness and ease-of-use • Large ecosystem evolving around CDI Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  12. 12. A Quick Look at CDI • Basic dependency injection • @Inject, @Qualifier, @Named, @Stereotype, @Alternative, @Produces, @Disposes • Context management • @RequestScoped, @SessionScoped, @ConversationScoped, @ApplicationScoped, @FlowScoped, @TransactionScoped • Lightweight Events • Event, @Observes • Interceptors/Decorators • @Interceptor, @Decorator • Portable Extensions SPI Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  13. 13. The Case for CDI • “Hibernate OGM is not expected to be the Rosetta stone used to interact with all NoSQL solutions in all use cases” • No real domain model • Advanced, highly specialized features • Unsupported NoSQL solutions • Existing NoSQL API knowledge • Most NoSQL APIs POJO based, easy to integrate natively via CDI Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  14. 14. CDI NoSQL Demo https://github.com/m-reza-rahman/cdi-nosql-demo Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
  15. 15. Summary • NoSQL has uses, but still immature, niche and volatile • JPA can apply well to NoSQL – many such initiatives • Most NoSQL APIs are good enough to integrate directly via CDI Copyright © 2015 CapTech Ventures, Inc. All rights reserved.
