                                    throws SnowflakeSQLException

Creates a storage client based on the value of stageLocationType

Parameters:

stageLocationType - The type of the stage, e.g. "S3"

stageCredentials - Map of stage credential properties

parallel - the degree of parallelism to be used by the client

encMat - encryption material for the client

stageRegion - the region where our stage is located

Returns:

a SnowflakeStorageClient interface to the instance created

Throws:

SnowflakeSQLException - if any error occurs

createStorageMetadataObj

public StorageObjectMetadata createStorageMetadataObj(String stageLocationType)

Creates a storage provider specific metadata object, accessible via the platform independent interface

Parameters:

stageLocationType - determines the implementation to be created

Returns:

the implementation of StorageObjectMetadata
