JNoSQL/Diana/Hbase

Hbase

HBase is an open source, non-relational, distributed database modeled after Google's BigTable and is written in Java.

Maven Project

To use HBase driver in a Maven Project:

        <dependency>
            <groupId>org.jnosql.diana</groupId>
            <artifactId>hbase-driver</artifactId>
            <version>version</version>
        </dependency>

E.g:

        <dependency>
            <groupId>org.jnosql.diana</groupId>
            <artifactId>hbase-driver</artifactId>
            <version>0.0.1</version>
        </dependency>

Column

The HBase column implementation uses the HBaseColumnConfiguration to a configuration. This class has configurations methods such as host, port, timeout, user, password.

Sample Code

public class App {

    public static final String KEY_SPACE = "newKeySpace";
    public static final String COLUMN_FAMILY = "newColumnFamily";

    public static void main(String[] args) {

        ColumnConfiguration condition = new HBaseColumnConfiguration();

        try(ColumnFamilyManagerFactory managerFactory = condition.get()) {
            ColumnFamilyManager columnEntityManager = managerFactory.get(KEY_SPACE);
            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)));

            columnEntityManager.save(entity);

            ColumnQuery query = select.from(COLUMN_FAMILY).where(ColumnCondition.eq(id)).build();
            Optional<ColumnEntity> result = columnEntityManager.singleResult(query);
            System.out.println(result);

        }


    }
}
