Snap type: | Write |
---|
Description: | This Snap reads binary data passed as binary objects from its input view and creates a .zip file at a specified file destination. Note: Currently, this Snap supports only the .zip format. - Expected upstream Snaps: Any Snap that produces binary data in the output view, such as File Reader, or Unzip.
- Expected downstream Snaps: Downstream Snap is optional. Any Snap with a document input view can be connected downstream.
- Expected input: Any binary data stream to be zipped
- Expected output: The output view for this Snap is optional. If an output view is open and the zip file write action is successful, the output view provides a document with information on the filename, result, and original data. An example is:
Code Block |
---|
{
"filename": "ftp://ftp.Snaplogic.com/home/qatest/sample.zip",
"result": "overwritten"
} |
The value of the "result" field can be "overwritten" or "created" or "ignored". The value "ignored" indicate that the Snap did not overwrite the existing file because the value of the File action property is "IGNORE". |

Support and limitations: | Does not work in in Ultra Pipelines. |
---|
Known Issues: | This Snap does not create an output file when using the input from SAS Generator Snap configured with only the DELETE SAS permission. This is not the case when the target file exists. |
---|
Account: | This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. This Snap supports a Basic auth account, an AWS S3 auth account, SSH Auth account, SMB account, or no account. See Configuring Binary Accounts for information on setting up accounts that work with this Snap. Account types supported by each protocol are as follows: Protocol | Account types |
---|
sldb | no account | s3 | AWS S3 | ftp | Basic Auth | sftp | Basic Auth, SSH Auth | ftps | Basic Auth | hdfs | no account | http | no account | https | no account | smb | SMB | wasb | Azure Storage | wasbs | Azure Storage | gs | Google Storage |
Note |
---|
The FTPS file protocol works only in explicit mode. The implicit mode is not supported. |
Required settings for account types are as follows: Account Type | Settings |
---|
Basic Auth | Username, Password | AWS S3 | Access-key ID, Secret key | SSH Auth | Username, Private key, Key Passphrase | SMB | Domain, Username, Password | Azure Storage | Account name, Primary access key | Google Storage | Approval prompt, Application scope, Auto-refresh token (Read-only properties are Access token, Refresh token, Access token expiration, OAuth2 Endpoint, OAuth2 token and Access type.) |
|
---|
Views: |
Input | This Snap has at least one binary input view from which it gets the binary data to be written to the zip file specified in the File name property. |
---|
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. |
---|
File name
| Required. Specifies the URL of the file where the output binary data is written. The supported file protocols are: - sldb:
- http:
- sftp:
- ftp:
- ftps:
- s3:
- hdfs:
- webdhfs:
- smb:
- wasb:
- wasbs:
- gs:
This property works similar to the File name property of the File Writer Snap. Please refer the Settings section of the File Writer Snap for additional information.
When using expressions to build a file name, ensure that the resulting file name does not contain characters that are not supported by the target platform. For example, a file name that contains the special character ":" is not supported in SMB. Note |
---|
When the Snap zips multiple binary data and when the File name property is an expression (such as $Filename), all file name values in the headers of the binary data should be the same. Otherwise, the Snap will throw an exception. |

File action
| Required. The action to perform if the file already exists. The options available include: - Overwrite: If Overwrite is selected, the Snap attempts to write the file without checking for the file's existence for better performance and the "fileAction" field will be "overwritten" in the output view data.
- Ignore: The Snap does not overwrite the existing file and will do nothing but write the status and file name to its output view.
- Error: If Error is selected, the error displays in the Pipeline Run Log. If an error view is defined, the error will be written there as well.

title | Write files to Azure Blob Storage along with Content Type |
---|
| You can 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 contents – application/zip, application/java-archive and so on; and pass it as the $content-type (case-sensitive) for the file.
|
Note |
---|
For wasb:// and wasbs:// file protocols, only the Overwrite file action is supported. |
Default value: Overwrite
|
---|
Base directory
| The root directory for all the files added to .zip file.
|
---|
Use input view label
| If true, the input view label is used for all names of the files added to the zip file. Otherwise, the input view ID is used instead, when input binary stream does not have its content-location in its header. When this option is selected, if there are more than one binary input streams in an input view, for the second input stream and after, the file names will be the input view label appended with '_n'. If the label is in the format of 'name.ext', '_n' will be append to the 'name', e.g. name_2.ext for the second input stream.
Example: If this option is selected, if Base directory is testFolder and the input view label is test.csv, the file name for the first binary input stream in that input view will be testFolder/test.csv, and the second, testFolder/test_2.csv, and the third, testFolder/test_3.csv, and so on.
Default value: Not selected |
---|
Number of retries | Specifies the maximum number of retry attempts when the Snap fails to write. If the value is larger than 0, the Snap first stores the input data in a temporary zip file before writing to the target file. Info |
---|
Ensure that the local drive has sufficient free disk space as large as the expected target file size. |
Example: 3 Minimum value: 0 Default value: 0 Multiexcerpt include macro |

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 |

- PublicReadWrite
- AuthenticatedRead
- LogDeliveryWrite
- BucketOwnerRead
- BucketOwnerFullControl
- AwsExecRead
