Overview

Snap type:

Read

Description:

This Snap unloads the result of a query to a file or files stored on the Snowflake stage, or on an external S3 workspace, or on Azure Storage Blob, if required. The target Snowflake table is not modified. Once the data is unloaded to the storage, users can get the file either using Snowflake GET or S3 file reader.

Expected upstream Snaps: Any Snap with a document output view

Expected downstream Snaps: Any Snap with a document input view, such as JSON Formatter, Mapper, and so on. The CSV Formatter Snap cannot be connected directly to this Snap since the output document map data is not flat.

Expected input: Key-value map data to evaluate expression properties of the Snap

Expected output: Document with Snowflake response, query command and the location Url for the unloaded file.

The Snap behaves the same on a Groundplex as it does in a Cloudplex.

Prerequisites:

You must have minimum permissions on the database to execute Snowflake Snaps. To understand if you already have them, you must retrieve the current set of permissions. The following commands enable you to retrieve those permissions:

SHOW GRANTS ON DATABASE <database_name>
SHOW GRANTS ON SCHEMA <schema_name>
SHOW GRANTS TO USER <user_name>

Security Prerequisites: You should have the following permission in your Snowflake account to execute this Snap:

Usage (DB and Schema): Privilege to use database, role, and schema.

The following commands enable minimum privileges in the Snowflake Console:

grant usage on database <database_name> to role <role_name>;
grant usage on schema <database_name>.<schema_name>;

For more information on Snowflake privileges, refer to Access Control Privileges.

The below are mandatory when using an external staging location:

When using an Amazon S3 bucket for storage:

The Snowflake account should contain S3 Access-key ID, S3 Secret key, S3 Bucket and S3 Folder.
The Amazon S3 bucket where the Snowflake will write the output files must reside in the same region as your cluster.

When using a Microsoft Azure storage blob:

A working Snowflake Azure database account.

Internal SQL Commands

This Snap uses the COPY INTO command internally. It enables unloading data from a table (or query) into one or more files in one of the following locations:

Named internal stage (or table/user stage).
Named external stage, that references external location, such as, Amazon S3, Google Cloud Storage, or Microsoft Azure.
External location, such as, Amazon S3, Google Cloud Storage, or Microsoft Azure.

Support and limitations:

Works in Ultra Task Pipelines.
Snowflake provides the option to use the Cross Account IAM into the external staging. You can adopt the cross account access through option Storage Integration. With this setup, you don’t need to pass any credentials around and access the storage only using the named stage or integration object. For more details: Configuring Cross Account IAM Role Support for Snowflake Snaps.

Account:

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. This Snap requires a Snowflake Account with S3 or Microsoft Azure properties. See Snowflake Account for information on setting up this type of account.

Views:

Input	This Snap has at most one document input view.
Output	This Snap has at most one document output view.
Error	This Snap has at most one document error view and produces zero or more documents in the view.

Settings

Label

Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Query

Required. Defines a SELECT query. The results of the query are unloaded. In most cases, it is worthwhile to unload data in sorted order by specifying an ORDER BY clause in the query; this approach will save the time Required. to sort the data when it is reloaded.

Example: SELECT * FROM public.company ORDER BY id

Default value: None

Staging Location

The staging location for the unload. The expected input for this should be a path to a file or filename-prefix.

The options available include:

External: Location that is not managed by Snowflake. The location should be an AWS S3 Bucket or Microsoft Azure Storage blob.
Internal: Location that is managed by Snowflake.

Default value: Internal

Target

Required. The staging area where the unloaded file(s) are placed. If the staging location is external, it will be put under the S3 Bucket or Microsoft Azure Storage Blob specified for the Account. If the staging location is internal, the files will be placed in the user’s home folder.

Example: TestFolder/file_name_prefix

Default value: None

Storage Integration

The pre-defined storage integration is used to authenticate the external stages.

Default value: None

File Format Type

The format type for the unloaded file. The options available are None, CSV, and CUSTOMIZED.

If CUSTOMIZED is chosen, then the customized format identifier must be specified.

Default value: None

Customized format identifier

The file format object to use for unloading data from the table. The field is valid only when the File format type is specified as Customized. Otherwise, this will be ignored.
Default value: None

File format option

Specify the file format option. Separate multiple options by using blank spaces and commas.

You can use various file format options including binary format which passes through in the same way as other file formats. See File Format Type Options for more information.

Before loading binary data into Snowflake, you must specify the binary encoding format, so that the Snap can decode the string type to binary types before loading into Snowflake. This can be done by specifying the following binary file format:

BINARY_FORMAT=xxx (Where XXX = HEX|BASE64|UTF-8)

However, the file you upload and download must be in similar formats. For instance, if you load a file in HEX binary format, you should specify the HEX format for download as well.

Default value: None

Copy options

Overwrite

If selected, the UNLOAD overwrites the existing files, if any, in the location where files are stored.

If unselected, the option does not remove the existing files or overwrite.

Default value: Not selected

Generate single file

If selected, the UNLOAD will generate a single file. If it is not selected, the filename prefix needs to be included in the path.

Default value: Not selected

Max file size

Maximum size (in bytes) of each file to be generated in parallel per thread. The number should be greater than 0, If it is less than or equals 0, the Snap will use the default size for snowflake: 16000000 (16MB).

Default value: 0

Encryption type

Specifies the type of encryption to be used on the data. The available encryption options are:

None: Files do not get encrypted.
Server Side Encryption: The output files on Amazon S3 are encrypted with server-side encryption.
Server-Side KMS Encryption: The output files on Amazon S3 are encrypted with an Amazon S3-generated KMS key.

Default value: No default value.

The KMS Encryption option is available only for S3 Accounts (not for Azure Accounts) with Snowflake.

KMS key

The KMS key that you want to use for S3 encryption. For more information about the KMS key, see AWS KMS Overview and Using Server Side Encryption.

Default value: No default value.

This property applies only when you select Server-Side KMS Encryption in the Encryption Type field above.

Include column headings

If selected, the table column heading will be included in the generated files. If multiple files are generated, the heading will be included in every file.

Default value: Not selected

Validation Mode

This mode is useful for visually verifying the data before unloading it. If this is NONE, validation mode is disabled or, the unloaded data will not be written to the file. Instead, it will be sent as a response to the output.

The options available include:

NONE
RETURN_ROWS

Default value: NONE

Manage Queued Queries

Select this property to decide whether the Snap should continue or cancel the execution of the queued Snowflake Execute SQL queries when you stop the pipeline.

If you select Cancel queued queries when the pipeline is stopped or if it fails, then the read queries under execution are canceled, whereas the write queries under execution are not canceled. Snowflake internally determines which queries are safe to be canceled and cancels those queries.

Default value: Continue to execute queued queries when the pipeline is stopped or if it fails

Snap execution

Page lookup error: page "Anaplan Read" not found.

If you're experiencing issues please see our Troubleshooting Guide.

Troubleshooting

The preview on this Snap will not execute the Snowflake UNLOAD operation. Connect a JSON Formatter and a File Writer Snaps to the error view and then execute the pipeline. If there is any error, you will be able to preview the output file in the File Writer Snap for the error information.

Examples

Unloading Data (Including Binary Data Types) From Snowflake Database

The following example Pipeline demonstrates how you can unload binary data as a file and load it into an S3 bucket.

First, we configure the Snowflake - Unload Snap by providing the following query:

select * from EMP2 – this query unloads data from EMP2 table.

Note that we set the File format option as BINARY_FORMAT='UTF-8' to enable the Snap to pass binary data.

Upon validation, the Snap shows the unloadRequest and unloadDestination in its preview.

We connect the JSON Formatter Snap to Snowflake - Unload Snap to transform the binary data to JSON format, and finally write this output to a file in S3 bucket using the File Writer Snap. Upon validation, the File Writer Output Snap writes the output (unload request)- the output preview is as shown below.

Download this Pipeline.

The following example illustrates the usage of the Snowflake Unload Snap.

In this example, we run the Snowflake SQL query using the Snowflake Unload Snap. The Snap selects the data from the table, @ADOBEDATA2 and writes the records to the table, adobedatanullif using the File Writer.

Connect the JSON formatter Snap to convert the predefined CSV file format to JSON and write the data using the File Writer Snap.

Successful execution of the pipeline gives the below output preview:

November 2022	431patches19220	08 Dec 2022	Latest	The Snowflake - Bulk Upsert Snap no longer supports values from an upstream input document in the Key columns field when the expression button is enabled. The value must remain constant throughout the Snap’s execution and now limits support for expressions to include only Pipeline parameters. To avoid breaking your existing Pipelines that use a value from the input schema in the Key columns field, update the Snap settings to use an input value from Pipeline parameters instead. The Snowflake Bulk Load Snap no longer displays the validation warning in the following cases: When you configure the Validation Mode as NONE and Validation Errors Type as Do not show errors in the Snap, or When Validation Mode is RETURN_n_ROWS, RETURN_ERRORS, or RETURN_ALL_ERRORS.
November 2022	main18944	10 Nov 2022	Stable	The Snowflake - Bulk Load Snap now routes the `403-Access Denied` error to the error view (when the error view is enabled) when you do not have `DeleteObject` permission to delete the temporary files in the S3 bucket. Fixed the following issues in the Snowflake - Bulk Load Snap: The Snap failed when the Preserve case sensitivity field was not selected and the column names in the input document and the target table were the same but the cases were different. Now, the Snap does not fail and loads the data correctly to the target table. The Snap created a table when it did not exist with multiple columns in the target table when there were two input views, but the column name cases were different in both views. Now, the Snap creates the table from the metadata provided by the second input view and loads the data into the target table from the first input view. The Snowflake Insert Snap now creates the target table only from the table metadata of the second input view when the following conditions are met: The Create table if not present checkbox is selected. The target table does not exist. The table metadata is provided in the second input view.
November 2022	430patches18911	08 Nov 2022	Latest	Because of performance issues, all Snowflake Snaps now ignore the Cancel queued queries when pipeline is stopped or if it fails option for Manage Queued Queries, even when selected. Snaps behave as though the default Continue to execute queued queries when the Pipeline is stopped or if it fails option were selected.
October 2022	430patches18781	27 Oct 2022	Latest	The Snowflake Insert and Snowflake Bulk Upsert Snaps now do not fail with the `SQL Operation failed` error, when you insert the uppercase key name into a mixed-case column if the Preserve case sensitivity checkbox is deselected. The Snowflake Bulk Load Snap now works as expected when you configure On Error with SKIP_FILE_error_percent_limit% and set the Error Percent Limit to more than the percentage of rows with invalid data in the CSV file.
October 2022	430patches18432	13 Oct 2022	Latest	The Snowflake Bulk Load Snap now has a Validation Errors Type dynamic field, which provides options for displaying validation errors. You can now choose Aggregate errors per row to display a summary view of errors.
September 2022	430patches17962	19 Sep 2022	Latest	The Snowflake Bulk Load Snap now triggers the metadata query only once even for invalid input, thereby improving the performance of Snap.
September 2022	430patches17894	15 Sep 2022	Latest	The Snowflake Select Snap now works as expected when the table name is dependent on an upstream input.
August 2022	430patches17748	02 Sep 2022	Latest	Fixes in the Snowflake Bulk Load Snap: The Snap now routes the `403-Access Denied` error to the error view (when the error view is enabled) when you do not have `DeleteObject` permission to delete the temporary files in the S3 bucket. The Snap now checks for the expiration time whenever it receives a new access token for refreshing the token in Snowflake OAuth2 account.
August 2022	430patches17377	25 Aug 2022	Latest	The following issues are fixed in the Snowflake - Bulk Load Snap: The Snap successfully loads the data even when you deselect the Preserve case- sensitivity checkbox and the source and target column names are similar, but with different casing. When the Snap has two input views, it creates the target table from the metadata provided by the second input view and loads the data into the target table from the first input view. The Snowflake Select Snap now validates successfully even when you set the Table Name field with an expression.

4.29 Patch	429patches16458	27 Jun 2022	Latest	Fixed the following issues with the Snaps that use Snowflake Accounts Key Pair Authentication. The Snaps were not able to read the private keys provided as Pipeline parameters, because the key was malformed by replacing the line breaks with whitespace characters. Now, the private keys are properly formed and read when provided as Pipeline parameters. The Snap displayed a Null Point Exception error when you pass an invalid key into the Private Key field like test. Now, the Snap displays a valid error message. Fixed an issue with the Snaps due to an upgrade made to HikariCP that caused a conditional failure and prevented the downstream Snaps to supply the parameters to the stored procedure. Fixed an issue with Snowflake Execute and Snowflake Select Snaps where the Snap displayed an exception error when the FLOAT or DOUBLE datatype column has the value as NaN (Not a Number). Now the output value is written as-is (NaN) for FLOAT or DOUBLE datatype column and does not display an exception. Enhanced the following Snowflake Accounts with support for Key Pair Authentication. Snowflake Azure Database Account Snowflake Google Storage Database Account Snowflake S3 Database Account Snowflake S3 Dynamic Account Removed support for unencrypted Private Keys to enforce security in Snowflake accounts.

4.21	snapsmrc542	09 May 2020	Stable	Upgraded with the latest SnapLogic Platform release.
4.20 Patch	db/snowflake8800	14 Apr 2020	Latest	Certifies the Snowflake Snap Pack against JDBC Driver version 3.12.3. Snowflake Execute and Multi-Execute Snaps may break existing Pipelines if the JDBC Driver is updated to a newer version. With the updated JDBC driver (version 3.12.3), the Snowflake Execute and Multi-Execute Snaps' output displays a Status of "-1" instead of "0" without the Message field upon successfully executing DDL statements. If your Pipelines use these Snaps and downstream Snaps use the Status field's value from these, you must modify the downstream Snaps to proceed on a status value of -1 instead of 0. This change in the Snap behavior follows from the change introduced in the Snowflake JDBC driver in version 3.8.1: "Statement.getUpdateCount() and PreparedStatement.getUpdateCount() return the number of rows updated by DML statements. For all other types of statements, including queries, they return -1."
4.20 Patch	db/snowflake8758	03 Mar 2020	Latest	Re-release of fixes from db/snowflake8687 for 4.20: Fixes the Snowflake Bulk Load snap where the Snap fails to load documents containing single quotes when the Load empty strings checkbox is not selected.
