Class SnowflakeFileTransferMetadataV1

java.lang.Object

net.snowflake.client.jdbc.SnowflakeFileTransferMetadataV1

All Implemented Interfaces:

Serializable, SnowflakeFileTransferMetadata

public class SnowflakeFileTransferMetadataV1
extends Object
implements SnowflakeFileTransferMetadata, Serializable

A class to manage metadata for upload or download files. It is introduced for distributed data processing. The typical use case is: 1. The cluster master has JDBC connection to the Snowflake and it can generate this object for the file transfer. 2. The cluster master node can transfer the object to cluster worker. 3. The cluster worker can upload or download data with the object without JDBC Connection.

NOTE: When this class is created, it only supports UPLOAD for GCS. It is created for Snowflake Spark Connector.
