+/**
+ * IO to read and write data on Snowflake.
+ *
+ * <p>SnowflakeIO uses <a href="https://docs.snowflake.net/manuals/user-guide/jdbc.html">Snowflake
+ * JDBC</a> driver under the hood, but data isn't read/written using JDBC directly. Instead,
+ * SnowflakeIO uses dedicated <b>COPY</b> operations to read/write data from/to Google Cloud
+ * Storage.
+ *
+ * <p>To configure SnowflakeIO to read/write from your Snowflake instance, you have to provide a
+ * {@link DataSourceConfiguration} using {@link
+ * DataSourceConfiguration#create(SnowflakeCredentials)}, where {@link SnowflakeCredentials might be
+ * created using {@link org.apache.beam.sdk.io.snowflake.credentials.SnowflakeCredentialsFactory}}.
+ * Additionally one of {@link DataSourceConfiguration#withServerName(String)} or {@link
+ * DataSourceConfiguration#withUrl(String)} must be used to tell SnowflakeIO which instance to use.
+ * <br>
+ * There are also other options available to configure connection to Snowflake:
+ *
+ * <ul>
+ * <li>{@link DataSourceConfiguration#withWarehouse(String)} to specify which Warehouse to use
+ * <li>{@link DataSourceConfiguration#withDatabase(String)} to specify which Database to connect
+ * to
+ * <li>{@link DataSourceConfiguration#withSchema(String)} to specify which schema to use
+ * <li>{@link DataSourceConfiguration#withRole(String)} to specify which role to use
+ * <li>{@link DataSourceConfiguration#withPortNumber(int)} to specify custom port of Snowflake
+ * instance
+ * </ul>
+ *
+ * <p>For example:
+ *
+ * <pre>{@code
+ * SnowflakeIO.DataSourceConfiguration dataSourceConfiguration =
+ * SnowflakeIO.DataSourceConfiguration.create(SnowflakeCredentialsFactory.of(options))
+ * .withServerName(options.getServerName())
+ * .withWarehouse(options.getWarehouse())
+ * .withDatabase(options.getDatabase())
+ * .withSchema(options.getSchema);
