Simple Storage Service (S3) is an online data storage service provided by Amazon, which provides low-latency access through web services. For more information, see https://aws.amazon.com/s3/ .
- Read: Supported
- Write: Not supported
Before you begin, please verify that your Alteryx® environment meets the following requirements:
Integration: Your Alteryx instance is connected to a running environment supported by your product edition.
Multiple region : Multiple S3 connections can be configured in different regions.
Enable S3 Connectivityhas been enabled in the Workspace Settings Page.
- Acquire the Access Key ID and Secret Key for the S3 bucket or buckets to which you are connecting. For more information on acquiring your key/secret combination, contact your S3 administrator.
Access to S3 requires:
Each user must have appropriate permissions to access S3.
- To browse multiple buckets through a single S3 connection, additional permissions are required. See below.
- Authentication using IAM roles is not supported.
- Automatic region detection in the create and edit connection is not supported.
You can create additional S3 connections by the following method:
Create through application
You can create a S3 connection through the application.
- Login to the application.
- In the left navigation bar, click the Connections icon.
In the Create Connection page, click the External Amazon S3 card.
Specify the connection properties:
Property Description DefaultBucket
(Optional) The default S3 bucket to which to connect. When the connection is first accessed for browsing, the contents of this bucket are displayed.
If this value is not provided, then the list of available buckets based on the key/secret combination is displayed when browsing through the connection.
NOTE: To see the list of available buckets, the connecting user must have the getBucketList permission. If that permission is not present and no default bucket is listed, then the user cannot browse S3.
Access Key ID
Access Key ID for the S3 connection.
Secret Key for the S3 connection.
Server Side Encryption If server-side encryption has been enabled on your bucket, you can select the server-side encryption policy to use when writing to the bucket. SSE-S3 and SSE-KMS methods are supported. For more information, see http://docs.aws.amazon.com/AmazonS3/latest/dev/serv-side-encryption.html . Server Side Kms key Id
When KMS encryption is enabled, you must specify the AWS KMS key ID to use for the server-side encryption. For more information, see "Server Side KMS Key Identifier" below.
For more information on the other options, see Create Connection Window.
Server Side KMS Key Identifier
When KMS encryption is enabled, you must specify the AWS KMS key ID to use for the server-side encryption.
- Access to the key:
- Access must be provided to the authenticating user.
The AWS IAM role must be assigned to this key.
- Encrypt/Decrypt permissions for the specified KMS key ID:
- Permissions must be assigned to the authenticating user.
The AWS IAM role must be given these permissions.
- For more information, see https://docs.aws.amazon.com/kms/latest/developerguide/key-policy-modifying.html .
The format for referencing this key is the following:
You can use an AWS alias in the following formats. The format of the AWS-managed alias is the following:
The format for a custom alias is the following:
<FSR> is the name of the alias for the entire key.
Create via API
For more information on the vendor and type information to use, see Connection Types.

Java VFS Service
The Java VFS Service has been modified to handle an optional connection ID, enabling S3 URLs with connection ID and credentials. The other connection details are fetched through the Designer Cloud application to create the required URL and configuration.
Using S3 Connections
Uses of S3
The Designer Cloud Powered by Trifacta platform can use S3 for the following tasks:
Enabled S3 Integration: The Designer Cloud Powered by Trifacta platform has been configured to integrate with your S3 instance.
- Creating Datasets from S3 Files: You can read in source data stored in S3. An imported dataset may be a single S3 file or a folder of identically structured files. See Reading from Sources in S3 below.
- Reading Datasets: When creating a dataset, you can pull your data from a source in S3. See Creating Datasets below.
In the Designer Cloud application, S3 is accessed through the S3 browser. See S3 Browser.
NOTE: When Designer Cloud application executes a job on a dataset, the source data is untouched. Results are written to a new location, so that no data is disturbed by the process.
Before you begin using S3
Access: If you are using system-wide permissions, your administrator must configure access parameters for S3 locations. If you are using per-user permissions, this requirement does not apply.
/trifacta/uploadsfor reading and writing data. This directory is used by the Designer Cloud application.
Your administrator can grant access on a per-user basis or for the entire workspace.
The Designer Cloud Powered by Trifacta platform utilizes an S3 key and secret to access your S3 instance. These keys must enable access to the appropriate directories in the S3 instance.
NOTE: If you disable or revoke your S3 access key, you must update the S3 keys for each user or for the entire system.
Storing data in S3
Your administrator should provide raw data or locations and access for storing raw data within S3. All Alteryx users should have a clear understanding of the folder structure within S3 for each individual.
- Users should know where shared data is located and where personal data is stored without interfering with or confusing other users.
- The Designer Cloud application stores the results of each job in a separate folder in S3.
NOTE: Designer Cloud application does not modify source data in S3. Source data stored in S3 is read without modification from source locations, and source data uploaded to the Designer Cloud Powered by Trifacta platform is stored in
Reading from sources in S3
You can create an imported dataset from one or more files stored in S3.
NOTE: Import of glaciered objects is not supported.
You can parameterize your input paths to import source files as part of the same imported dataset. For more information, see Overview of Parameterization.
When you select a folder in S3 to create your dataset, you select all files in the folder to be included.
- This option selects all files in all sub-folders and bundles them into a single dataset. If your sub-folders contain separate datasets, you should be more specific in your folder selection.
- All files used in a single imported dataset must be of the same format and have the same structure. For example, you cannot mix and match CSV and JSON files if you are reading from a single directory.
When a folder is selected from S3, the following file types are ignored:
*_FAILEDfiles, which may be present if the folder has been populated by the running environment.
NOTE: If you have a folder and file with the same name in S3, search only retrieves the file. You can still navigate to locate the folder.
When creating a dataset, you can choose to read data in from a source stored from S3 or local file.
- S3 sources are not moved or changed.
- Local file sources are uploaded to
/trifacta/uploadswhere they remain and are not changed.
Data may be individual files or all of the files in a folder. In the Import Data page, click the S3 tab. See Import Data Page.
