Snowflake Driver4 min read
The Snowflake Driver is an open-source Java client library that connects to Snowflake to access the Snowflake database. This library supports various programming interfaces, such as JDBC and ODBC. It can also support Native programmatic interfaces and certificate chain evaluation.
The Snowflake Data Source Name helps to identify the connection. Other settings include the Hostname, Database Name, Schema, and Warehouse.
The role field specifies the default user role for sessions initiated by the driver. In addition, the driver requires the user to be assigned the role. It should be noted that TLS/SSL connections are required for secure connections with Snowflake.
JDBC Snowflake Driver:
The Snowflake Driver supports JDBC and can be used to connect to a Databricks data store. However, it must be configured properly and enabled before you can use it.
Then, you must provide the connection properties. For example, the TransportMode must be HTTP and the SSL should be 1.
The JDBC driver has a JAR file and is available in the Snowflake directory. You can integrate this library into a Java-based project using Maven.
However, you should ensure that you use the latest version. To do this, run the client application and call the Snowflake Driver’s CURRENT_CLIENT() method.
To use the Snowflake driver with JDBC, you must have a Snowflake account. After you have created a Snowflake account, you need to set up the Snowflake Driver’s JDBC driver. Once you have done that, you can start using the driver.
ODBC Snowflake Driver:
ODBC Snowflake Driver allows you to connect to the Snowflake database without having to install it separately. It works with both Windows and Mac OS. The ODBC driver creates an entry for LogLevel and LogPath automatically during the installation process, but does not create the Proxy entry by default.
If you want to bypass the proxy, you need to manually add an entry to your system’s registry. This driver provides an option to bypass the proxy by specifying the DSN name.
The ODBC Snowflake Driver supports a variety of SQL languages and is available for both 32-bit and 64-bit platforms.
It supports data from Snowflake and SQL, and it also supports popular BI tools. The driver requires Java SE 8 or higher and can be used with either OpenJDK or Oracle JDK.
ODBC Snowflake driver requires a few additional settings. First, you need to set the number of statements in a batch. The default number is one.
If you want to run multiple statements in one batch, you can specify a limit of two by setting the SQL_SF_STMT_ATTR_MULTI_STATEMENT_COUNT parameter. Then, call SQLExecute or SQLExecDirect.
Native programmatic interfaces:
Snowflake supports a range of popular programming languages and development platforms. You can use its client API and native programmatic interfaces to create powerful applications.
Native interfaces allow you to use Snowflake without any additional coding. For example, you can use the Snowflake client API to integrate Snowflake with your Java application.
Native programmatic interfaces for Snowflake support a number of authentication methods, including user-level authentication, federated authentication using SAML, and keypair authentication.
These methods all require browser access, and you can use password authentication, OAuth, keypair authentication, or native Okta authentication.
The native Snowflake Driver API supports multiple data sources, including tables and objects. Each data source can have a different set of Drivers. It can be a challenge for an administrator to monitor the Drivers across all applications.
Certificate chain evaluation:
The Snowflake driver uses OCSP (Online Certificate Status Protocol) to ensure that each certificate in the chain of trust is valid. OCSP is a standard protocol that runs over Port 80.
It’s often used by web applications to ensure that a web application’s certificates are not expired or revoked. It’s important to note that OCSP traffic is encapsulated within TLS traffic.
There are two types of Snowflake drivers. One type is a Snowflake driver that is meant for staging unencrypted files, while the other is a custom driver that can be used for staging unencrypted files. This option requires additional configuration. It also supports encryption.
Snowflake offers a powerful feature set that allows businesses to secure their data and ensure availability. Users can access Snowflake services using the credentials that Snowflake administrators provide.
The following topics provide information on how to perform data loading and unloading tasks, as well as best practices for data security.
When using a Snowflake driver, it’s important to understand the Snowflake definition of a database object. For example, a table may contain a view or sequence, while an index may be used to store data.
