SingleStore JDBC Driver (Preview)

Version: 0.1.0-preview

SingleStore JDBC Driver is a JDBC 4.2 compatible driver, used to connect applications developed in Java to SingleStore and MySQL databases. SingleStore JDBC Driver is LGPL licensed.

Status

Obtaining the driver

The driver (jar) can be downloaded from maven :

<dependency>
	<groupId>com.singlestore</groupId>
	<artifactId>singlestore-jdbc-client</artifactId>
	<version>0.1.0-preview</version>
</dependency>

Usage

To get a connection using SingleStore JDBC Driver, you need a connection string of the following format:

jdbc:singlestore:[replication:|loadbalance:|sequential:]//<hostDescription>[,<hostDescription>...]/[database][?<key1>=<value1>[&<key2>=<value2>]] 

The full list of parameters that can be used in the connection string is coming soon

Example:

"jdbc:singlestore://localhost:3306/test?user=root&password=myPassword"

You can then get a connection by using the Driver manager class:

Connection connection = DriverManager.getConnection("jdbc:singlestore://localhost:3306/test?user=root&password=myPassword");
Statement stmt = connection.createStatement();

ResultSet rs = stmt.executeQuery("SELECT NOW()");
rs.next();
System.out.println(rs.getTimestamp(1));

Another way to get a connection with SingleStore JDBC Driver is to use a connection pool.

• SingleStorePoolDataSource is an implementation that maintains a pool of connections. When a new connection is requested, one is borrowed from the pool.
• SingleStoreDataSource is a basic implementation that just returns a new connection each time the getConnection() method is called.

Example:

SingleStorePoolDataSource pool = new SingleStorePoolDataSource("jdbc:singlestore://server/db?user=myUser&maxPoolSize=10");

    try (Connection connection = pool.getConnection()) {
        try (Statement stmt = connection.createStatement()) {
            ResultSet rs = stmt.executeQuery("SELECT NOW()");
            rs.next();
            System.out.println(rs.getTimestamp(1));
        }
    }
