JDBC Driver#

Presto can be accessed from Java using the JDBC driver. Download presto-jdbc-0.265.1.jar and add it to the class path of your Java application.

The driver is also available from Maven Central:

<dependency>
    <groupId>com.facebook.presto</groupId>
    <artifactId>presto-jdbc</artifactId>
    <version>0.265.1</version>
</dependency>

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.

Name

Description

user

Username to use for authentication and authorization.

password

protocols

Comma delineated list of HTTP protocols to use. Example: protocols=http11. Acceptable values: http11,http10,http2

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 will be 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 that will be used 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.

KerberosConfigPath

Kerberos configuration file.

KerberosKeytabPath

Kerberos keytab file.

KerberosCredentialCachePath

Kerberos credential cache.

extraCredentials

Extra credentials for connecting to external services. The extraCredentials is a list of key-value pairs. Example: foo:bar;abc:xyz will create credentials abc=xyz and foo=bar

customHeaders

Custom headers to inject through JDBC driver. The customHeaders is a list of key-value pairs. Example: testHeaderKey:testHeaderValue will inject the header testHeaderKey with value testHeaderValue. Values should be percent encoded.
