About the Speakers

JNoSQL


NoSQL(Not Only SQL)

JNoSQL


What defines NoSQL databases?

� No fixed data structure

� Not an ACID, but a BASE

� Five different types

◦ Key/Value

◦ Column Family

◦ Document

◦ Graph

◦ Multi-Model

JNoSQL


ACID x BASE

Basically Available,Soft State,Eventual consistency

Atomicity,Consistency,Isolation,Durability

JNoSQL


Key/Value

� AmazonDynamo� AmazonS3

� Redis� Scalaris� Voldemort

� Couchbase� Hazelcast

Apollo Sun

Aphrodite Love

Ares War

Light Music

Beauty

JNoSQL


Row key

Column Family

� Hbase� Cassandra� Scylla� Clouddata� SimpleDb

� DynamoDB

Apollo

Ares

Kratos

Duty

{”Sun”, “Light”, ”Music”}

Duty“War”

SlainGods13

Weapon“Sword”

JNoSQL


Document

� AmazonSimpleD� Apache CouchDB

� Couchbase� MongoDB� Riak

{”name”:”Diana”,”father”:”Jupiter”,”mother”:”Latona”,”siblings”:{

”name”: ”Apollo”},”godOf”: {”Hunt”}

}

JNoSQL


Graph

� Neo4J� InfoGrid

� Sones� HyperGraphDB

Apollo

Ares

Kratos

JNoSQL


Multi-model

� OrientDB◦ graph, document

� Couchbase◦ key-value, document

� Elasticsearch◦ document, graph

� ArangoDB◦ column family, graph, key-value

JNoSQL


SQL -> NoSQL

SQL Key-Value Column Family

Document Graph

Table Bucket ColumnFamily

Collection

Row Key/Value pair

Column Document Vertex

Column Key/Value Pair

Key/Value Pair

Vertex/Edgeproperties

Relationship Link Edge

JNoSQL


How Java application interact with…

SQL NoSQLLogic

DAO

JPA

JDBC

JPA

JDBC

JPA

JDBC

Logic

DAO

JNoSQL


For example: for a Document DB…BaseDocument baseDocument = new BaseDocument();

baseDocument.addAttribute(name, value);

JsonObject jsonObject = JsonObject.create();

jsonObject.put(name, value);

Document document = new Document();

document.append(name, value);

ODocument document = new ODocument(“collection”);

document.field(name, value);

JNoSQL


A first attempt on independence…

Logic

DAO

JPA

� Hibernate OGM� Eclipse TopLink

JNoSQL


… brings a bunch of issues!

� Can’t save asynchronously◦ No callback

� Can’t define a Time to Live (TTL) for stored data� Consistency Level choice on persist� Not all DBs are SQL-based

� There are many NoSQL types

JNoSQL

JNoSQL


What is JNoSQL?

� Mapping API - Artemis

� Communication API - Diana

� No lock-in

� Divide and conquer

DAO

Mapping

JNoS

QL

JNoSQL


Eclipse JNoSQL

� Eclipse Foundation� Apache v2 + EPL 1.0

� API to each NoSQL type� Configurable� Extensible Communication

Mapping

JNoSQL


JNoSQL - Diana

� Communication layer API� One API for each DB type◦ Document

◦ Key-value

◦ Column

◦ Graph

JNoSQL


JNoSQL – Diana APIs

Key/Value Document

Column Family

Graph

JNoSQL


Back to that Document DB…

DocumentEntity entity = DocumentEntity.of("documentCollection");

Document document = Document.of(name, value);

entity.add(document);

JNoSQL


Names & Definitions

� Configuration� Factory� Manager� Entity

JNoSQL


Names & Definitions

ColumnConfiguration<?> condition = new DriverConfiguration();try(ColumnFamilyManagerFactory managerFactory = condition.get()) {

ColumnFamilyManager entityManager = managerFactory.get(KEY_SPACE);entityManager.insert(entity);

ColumnQuery select = select().from(COLUMN_FAMILY).where(eq(id)).build();ColumnDeleteQuery delete = delete().from(COLUMN_FAMILY)

.where(eq(id)).build();

Optional<ColumnEntity> result = entityManager.singleResult(query);entityManager.delete(delete);

}

JNoSQL


Handling diversity (1)

ColumnEntity entity = ColumnEntity.of(COLUMN_FAMILY);Column id = Column.of("id", 10L);

entity.add(id);entity.add(Column.of("version", 0.001));entity.add(Column.of("name", "Diana"));entity.add(Column.of("options", Arrays.asList(1, 2, 3)));

JNoSQL


Handling diversity (2)

//mutiple implementation

entityManager.insert(entity);

ColumnQuery query = select().from(COLUMN_FAMILY).where(ColumnCondition.eq(id)).build();

Optional<ColumnEntity> result = entityManager.singleResult(query);

//cassandra only

List<ColumnEntity> entities = entityManagerCassandra.cql("select * from newKeySpace.newColumnFamily where id=10;");

entityManagerCassandra.insert(entity, ConsistencyLevel.ALL);

JNoSQL


JNoSQL - Artemis

� Based on CDI and Diana � Heavy use of Annotations

� Events on Create, Update, Delete� Bean Validation Support� Configurable and Extensible

� “Query by Methods”

JNoSQL


Names & Definitions

� Annotated Entities� Template� Repository� Configuration

JNoSQL


Annotaded Entities

� MappedSuperclass� Entity� Column

@Entity(”god")public class God {

@Columnprivate String name;

@Columnprivate Set<God> siblings;

…}

JNoSQL


Templateimport static DocumentQuery.select;@Inject DocumentTemplate template;

God diana = God.builder().withName(“Diana”);template.insert(diana);template.update(diana);

DocumentQuery query = select().from(“god”).where(“name”).equals(“Diana”).build();List<God> gods = template.select(query);

JNoSQL


Repository

@Inject@Database(DatabaseType.COLUMN)private GodRepository godRepository;

@Inject@Database(DatabaseType.KEY_VALUE)private GodRepository godRepository;

JNoSQL


Configuration

[ {"description": "The couchbase document configuration","name": "document","provider":

"org.jnosql.diana.couchbase.document.CouchbaseDocumentConfiguration","settings": {"couchbase-host-1": "localhost","couchbase-user": "root","couchbase-password": "123456"

}} ]

JNoSQL


Configuration

@Inject@ConfigurationUnitprivate DocumentCollectionManagerFactory<?> entityManager;

JNoSQL


Expansibility

@Entity("person")public class God {

@Columnprivate String name;

@UDT(”weapon")@Columnprivate Weapon weapon;

}

JNoSQL


Expansibility

interface GodRepository extends CassandraRepository<God> {

@CQL("select * from Person")List<Person> findAll();

@CQL("select * from Person where name = ?")List<Person> findByName(String name);

}
