S3 File Reader

On this Page

Snap Type:Read
Description:

This Snap reads any type of data from an S3 bucket. If a value is given in the Version ID property, it will read the specific version of an S3 file object. The suggest features can be used to view and select S3 buckets, sub-directories, files, and version IDs.

ETL Transformations & Data Flow

This Snap extracts data from S3 buckets. 

Input & Output

  • Expected input: An upstream Snap is optional and any Snap with a document output view can be connected upstream (such as Mapper, File Writer, and so on). Any document with key-value pairs to evaluate expression properties in the S3 File Reader Snap. Each input document, if any, will cause one read operation of the Snap.
  • Expected output: Any Snap with a binary input view can be connected downstream, such as CSV Parser, JSON Parser, XML Parser, and so on. Binary data read from AWS S3 specified in the File property with header information about the binary stream. The binary data and header information can be previewed at the output of the Snap. An example is:

Prerequisites

IAM Roles for Amazon EC2

The IAM_CREDENTIAL_FOR_S3 feature is to access S3 files from Groundplex nodes hosted in the EC2 environment without Access-key ID and Secret key in the AWS S3 account in the Snap. The IAM credential stored in the EC2 metadata provides access rights to the S3 buckets. 

 Steps to enable the IAM_CREDENTIAL_FOR_S3 feature
  1. Open Manager.
  2. Open the Snaplexes tab of the project that contains the EC2-based Groundplex.
  3. Click the Groundplex to open its Properties.
  4. Open the Node Properties tab.
  5. Click + to add a new row in the Global properties section.
  6. Enter jvm_options in Key and -DIAM_CREDENTIAL_FOR_S3=TRUE in Value.

  7. Restart the JCC (node).
  • IAM role is supported only in the Groundplex nodes hosted in the EC2 environment.
  • The IAM Role stored on the EC2 instance requires List, Read, and Write permissions.

  • S3 account validation is not supported when you enable IAM role property. 

For more information on IAM Roles, see IAM Roles for Amazon EC2.

Support and Limitations

Works in Ultra Pipelines.

The current Snap functionality supports AWS S3 Cloud Service and will be applicable for AWSGovCloud setup.

Configurations

Account & Access

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Configuring Binary Accounts for information on setting up accounts that work with this Snap.

Required settings for account types are as follows: 

  • AWS S3 - Access-key ID, Secret key, Security token.
  • S3 Dynamic - Access-key ID, Secret key, Security token, Server-side encryption.

Views

InputThis Snap has at most one document input view. 
OutputThis Snap has exactly one binary output view.
ErrorThis Snap has at most one document error view and produces zero or more documents in the view.
Troubleshooting:The section describes typical issues you may encounter while using this Snap, and instructions on how to workaround them:

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.
File

Required. This property specifies the URL for the S3 file, from where the binary data is to be read. It must start with "s3:///". The suggest feature can be used to view the list of buckets, subdirectories and files. Bucket names are suggested if the property is empty or "s3:///". Once a bucket is selected, it can list subdirectories and files immediately below the bucket. Names of subdirectories end with a forward slash ("/"). The suggest feature is not supported if the properties in the S3 Dynamic account are parameters.

Prerequisite

The provided account must have 'read' access to the specified S3 bucket in order to read the file successfully.

Using Expressions:

This property can be an expression with the "=" button pressed.

For example, if the File property is "s3:///mybucket/out_" + Date.now() + ".csv" then the evaluated filename is s3:///mybucket/out_2013-11-13T00:22:31.880Z.csv.

Syntax:

For region names and their details, see AWS Regions and Endpoints.

Region Name

Region name is optional only if the region is us-east-1. In all other cases the region name must be specified based on the syntax above. For example, mybucket@eu-west-1. 

See AWS Regions and Endpoints for details.

Examples

  • s3:///mybucket@s3.eu-west-1.amazonaws.com/test.json
  • s3:///rds-sql-test-staging@s3.us-gov-east-1.amazonaws.com/test.csv
  • _filename (A key/value pair with "filename" key should be defined as a pipeline parameter)
  • $filename (A key/value pair with "filename" key should be defined the input document)

Default value:  s3:///

Version ID

Enter or select S3 file version ID. If the property is empty, the Snap reads the latest version. The suggest feature can be used to view the list of version IDs for the S3 file in the File property. The suggest feature is not supported if the properties in the S3 Dynamic account are parameterized. Each line in the suggested list also includes the last modified date and the file size to help select a version. When the property value is entered manually, only the version ID is needed. The Snap ignores the last modified date and size information of a version when it reads the file. If the versioning of a S3 bucket is not enabled, no version ID is suggested. The versions of the following cases will be omitted in the suggested list since their files cannot be downloaded: 

  • If a file had existed before the versioning was enabled, its version does not have any version ID assigned to it.
  • Version ID's with 'Deleted Marker' resource type are also omitted in the suggested list.

Examples:   xvcnB8gPi37l3hbOzlsRFxjVwQ.numQz

Default value:  [None]

Version ID suggestion intervalEnter the time interval for the Version ID suggestion. Enter two rows to provide a start date and an end dates. If only one row is provided, the interval will be from the date until now. If empty, all version IDs will be suggested. This property may be useful when a given S3 file has many versions. This property is used for the Version ID suggestion only, and not used during the Snap preview or execution.
Year

Enter the year as a 4-digit integer.

Example:  2017

Default value:  [None]

Month

Enter the month as an integer.

Examples:   9, 09, 12, and so on.

Default value:  [None]

Date

Enter the day of the month.

Examples:   28, 09, 12, and so on.

Default value:  [None]

Zone

Enter or select a time zone ID from the suggested list. May be empty for UTC. Please note only zone IDs in the suggested list are supported.

Examples:   US/Pacific

Default value:  [None]

Enable staging

If selected, the Snap downloads the source file into a local temporary file. When the download is completed, it streams the data from the temporary file to the output view. This property prevents the Snap from being blocked by slow downstream pipeline. The local disk should have sufficient free space as large as the expected file size. 

Default value: Not selected

Some Snaps may take a long time to process large amounts of data. This, in turn, could lead to connection timeouts, causing the pipeline to fail. Selecting this property saves the data on your local disk, enabling you to avoid such timeouts.

Number of retries

Specifies the maximum number of retry attempts that the Snap must make in case there is a network failure, and the Snap is unable to read the target file.

If the value is larger than 0, the Snap overrides the Enable staging value to true and downloads the S3 file to a temporary local file. If any error occurs during the download, the Snap waits for the time specified in the Retry interval and attempts to download the file again from the beginning. When the download is successful, the Snap starts to stream the data from the temporary file to the downstream Pipeline. All temporary local files are deleted when they are no longer needed.

Ensure that the local drive has sufficient free disk space to store the temporary local file.

Example:  3

Minimum value: 0

Default value: 0

Multiexcerpt "retries" not found. The page must be published before a preview can be rendered. Or, if you just created the macro, try refreshing the page.

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

Retry interval (seconds)

Specifies the minimum number of seconds for which the Snap must wait before attempting recovery from a network failure.

Example:  3

Minimum value: 1

Default value: 1

Get Object Tags

Select this check box to include object tags in the header of the output binary data. See Object Tagging for more information on object tags.

You must have the S3:GetObjectTagging permission to be able to use this feature.

Default value: Not selected

Snap Execution

Select one of the three modes in which the Snap executes. Available options are:

  • Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.
  • Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Examples

As of  we have discovered an issue with this Binary patch affecting the PGP Decrypt Snap. In case your Pipelines use the PGP Decrypt Snap, we recommend you to NOT use this patch. Else, your Pipelines will likely fail. We're working on a fix and will be deploying a Snap patch soon.

4.25 Patch425patches9564
 
Latest

Enhanced the SFTP session in Binary Snaps to support the SFTP servers which close SFTP sessions slowly.

4.25main9554
 
Stable

Enhanced the S3 File Writer Snap with an ability to write S3objects with Access Control List (ACL) details in a single API call.

In the 4.23 release, the S3 File Writer Snap used to write an S3 file and then set ACL if the ACL property was not empty. If the file write was successful and the ACL setting failed, both the output document in the output view and the error document in the error view was displayed. This issue has been resolved in the 4.24 release by enabling the Snap to configure ACL while writing the file. Therefore, the Snap produces an error document in the error view if the ACL configuration fails, irrespective of whether the file write action passes or fails.

4.24 Patch424patches9044-Latest

Enhanced the File Writer and S3 File Writer to use an MD5 checksum that automatically checks for data integrity and corruption while uploading the file.

Do not use the 423patches7923 build for the File Writer Snap, because it causes connectivity issues with the Snaplex nodes.

4.23 Patch423patches7795-Latest

Fixed an issue with File Writer Snap by skipping the validation of the SAS URI having write permission, if the SAS URI uses an access policy.

4.23 Patch423patches7660-Latest

Enhanced the File Poller Snap by adding a field, Exit on first matches, which when set to true stops the Snap from executing after the first file paths matching the filter are written to the output view. If the field is not configured or is set to false (default value), then the Snap continues to poll the directory until the Polling timeout is reached.

4.23main7430-Stable

Enhanced the ZipFile Write Snap to provide the ability to change the default content-type (application/octet-stream) for any file that is stored into the Azure Blob Storage (WASB: or WASBS: file protocol). Hence, the files that the ZipFile Write Snap writes into the Blob Storage can be saved with content-type asapplication/zipor any other type instead of application/octet-streamalways.

You can now prevent the Snap from writing files always to Azure Blob Storage (WASB: or WASBS: file protocol) with the application/octet-stream content-type. To do so, configure a binary header property in an upstream Snap, such as JSON Formatter or Mapper, to match the file's content – application/zipapplication/java-archive and so on; and pass it as the $content-type (case-sensitive) for the file.
