OrientDB is a NoSQL DBMS that support a subset of SQL ad query language.

NOTE: to use SNAPSHOT version remember to add the Snapshot repository to your pom.xml
.
The driver is registered to the Java SQL DriverManager and can be used to work with all the OrientDB database types:
The driver's class is com.orientechnologies.orient.jdbc.OrientJdbcDriver
. Use your knowledge of JDBC API to work against OrientDB.
Properties info = new Properties();
info.put("user", "admin");
info.put("password", "admin");
Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:localhost/test", info);
Then execute a Statement and get the ResultSet:
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT stringKey, intKey, text, length, date FROM Item");
rs.next();
rs.getInt("@version");
rs.getString("@class");
rs.getString("@rid");
rs.getString("stringKey");
rs.getInt("intKey");
rs.close();
stmt.close();
The driver retrieves OrientDB metadata (@rid,@class and @version) only on direct queries. Take a look at tests code to see more detailed examples.
By default a new database instance is created every time you ask for a JDBC connection. OrientDB JDBC driver provides a Connection Pool out of the box. Set the connection pool parameters before to ask for a connection:
Properties info = new Properties();
info.put("user", "admin");
info.put("password", "admin");
info.put("db.usePool", "true"); // USE THE POOL
info.put("db.pool.min", "3"); // MINIMUM POOL SIZE
info.put("db.pool.max", "30"); // MAXIMUM POOL SIZE
Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:localhost/test", info);
