2.3. JDBC Driver#

Presto can be accessed from Java using the JDBC driver. Download presto-jdbc-334.jar and add it to the class path of your Java application.

The driver is also available from Maven Central:

<dependency>
    <groupId>io.prestosql</groupId>
    <artifactId>presto-jdbc</artifactId>
    <version>334</version>
</dependency>

Requirements#

The JDBC driver is compatible with Java 8, and can be used with applications running on Java virtual machines version 8 and higher.

Driver Name#

The driver class name is io.prestosql.jdbc.PrestoDriver. Most users do not need this information as drivers are loaded automatically.

Connecting#

The following JDBC URL formats are supported:

jdbc:presto://host:port
jdbc:presto://host:port/catalog
jdbc:presto://host:port/catalog/schema

For example, use the following URL to connect to Presto running on example.net port 8080 with the catalog hive and the schema sales:

jdbc:presto://example.net:8080/hive/sales

The above URL can be used as follows to create a connection:

String url = "jdbc:presto://example.net:8080/hive/sales";
Connection connection = DriverManager.getConnection(url, "test", null);

Connection Parameters#

The driver supports various parameters that may be set as URL parameters, or as properties passed to DriverManager. Both of the following examples are equivalent:

// URL parameters
String url = "jdbc:presto://example.net:8080/hive/sales";
Properties properties = new Properties();
properties.setProperty("user", "test");
properties.setProperty("password", "secret");
properties.setProperty("SSL", "true");
Connection connection = DriverManager.getConnection(url, properties);

// properties
String url = "jdbc:presto://example.net:8080/hive/sales?user=test&password=secret&SSL=true";
Connection connection = DriverManager.getConnection(url);

These methods may be mixed; some parameters may be specified in the URL, while others are specified using properties. However, the same parameter may not be specified using both methods.

Parameter Reference#

Name	Description
`user`	Username to use for authentication and authorization.
`password`	Password to use for LDAP authentication.
`socksProxy`	SOCKS proxy host and port. Example: `localhost:1080`
`httpProxy`	HTTP proxy host and port. Example: `localhost:8888`
`clientInfo`	Extra information about the client.
`clientTags`	Client tags for selecting resource groups. Example: `abc,xyz`
`traceToken`	Trace token for correlating requests across systems.
`applicationNamePrefix`	Prefix to append to any specified `ApplicationName` client info property, which is used to set the source name for the Presto query. If neither this property nor `ApplicationName` are set, the source for the query is `presto-jdbc`.
`accessToken`	Access token for token based authentication.
`SSL`	Use HTTPS for connections
`SSLKeyStorePath`	The location of the Java KeyStore file that contains the certificate and private key to use for authentication.
`SSLKeyStorePassword`	The password for the KeyStore.
`SSLTrustStorePath`	The location of the Java TrustStore file to use. to validate HTTPS server certificates.
`SSLTrustStorePassword`	The password for the TrustStore.
`KerberosRemoteServiceName`	Presto coordinator Kerberos service name. This parameter is required for Kerberos authentication.
`KerberosPrincipal`	The principal to use when authenticating to the Presto coordinator.
`KerberosUseCanonicalHostname`	Use the canonical hostname of the Presto coordinator for the Kerberos service principal by first resolving the hostname to an IP address and then doing a reverse DNS lookup for that IP address. This is enabled by default.
`KerberosServicePrincipalPattern`	Presto coordinator Kerberos service principal pattern. The default is `${SERVICE}@${HOST}`. `${SERVICE}` is replaced with the value of `KerberosRemoteServiceName` and `${HOST}` is replaced with the hostname of the coordinator (after canonicalization if enabled).
`KerberosConfigPath`	Kerberos configuration file.
`KerberosKeytabPath`	Kerberos keytab file.
`KerberosCredentialCachePath`	Kerberos credential cache.
`extraCredentials`	Extra credentials for connecting to external services, specified as a list of key-value pairs. For example, `foo:bar;abc:xyz` creates the credential named `abc` with value `xyz` and the credential named `foo` with value `bar`.
`roles`	Authorization roles to use for catalogs, specified as a list of key-value pairs for the catalog and role. For example, `catalog1:roleA;catalog2:roleB` sets `roleA` for `catalog1` and `roleB` for `catalog2`.
`sessionProperties`	Session properties to set for the system and for catalogs, specified as a list of key-value pairs. For example, `abc:xyz;example.foo:bar` sets the system property `abc` to the value `xyz` and the `foo` property for catalog `example` to the value `bar`.
