Snap type:

Read

Description:

This Snap polls the target directory and looks for file names matching the specified pattern. It continues polling at the intervals specified in the Polling interval property until the timeout (specified in the Polling timeout property) is reached. Once polling is done, the Snap lists all files whose names match the specified pattern.

This Snap polls the target directory only; subdirectories, if any, are ignored. Use the Directory Browser Snap if you want to poll files in the directory and all subdirectories, as well as to poll a directory only once.

The File Poller Snap can be used in situations where an operation must be triggered when a specific file is found in the target directory. The pipeline can be configured with additional Snaps to process the Snap's output and delete the matched file before the Polling interval value is reached.

Expected upstream Snaps: Any Snap with a document output view, such as Mapper, JSON Generator.
Expected downstream Snaps: Any Snap with a document input view, such as File Reader, Mapper, JSON Formatter.
Expected input: An optional document to evaluate expressions in the Directory and/or File filter properties. Note that each input document will trigger the execution of the Snap.
Expected output: A full path in each document as a value for a key "path". If there are multiple files matching the filter, the same number of documents will be provided in the output view after each interval.

Prerequisites:

IAM Roles for Amazon EC2

The 'IAM_CREDENTIAL_FOR_S3' feature is to access S3 files from EC2 Groundplex, without Access-key ID and Secret key in the AWS S3 account in the Snap. The IAM credential stored in the EC2 metadata is used to gain the access rights to the S3 buckets. To enable this feature, the following line should be added to global.properties and the jcc (node) restarted:
jcc.jvm_options = -DIAM_CREDENTIAL_FOR_S3=TRUE

Please note this feature is supported in the EC2-type Groundplex only.

For more information on IAM Roles, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

Support and limitations:

Modes

Ultra pipelines: Works in Ultra Pipelines.
Spark mode: Not supported in Spark mode.

Limitation

For S3 folders, the Snap currently supports polling the target directory for a maximum of 10,000 files. If there are more than that, the Snap does not provide any output.

Account:

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. This Snap supports several account types, as listed in the table below, or no account. See Binary Account for information on setting up these types of accounts. 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
webhdfs	no account
smb	SMB
wasb	Azure Storage
wasbs	Azure Storage
gs	Google Storage
file	Local file system

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
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 most one document input view.
Output	This Snap has exactly one document output view.
Error	This Snap has at most one document error 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.

Directory

This property is a URL path to the directory where files will be searched. The expected syntax is:

[protocol]://[host][:port]/[path]

The supported file protocols are:

s3:
file:
ftp:
ftps:
sftp:
hdfs:
webhdfs:
sldb:
smb:
wasb:
wasbs:
gs:

Example:

- s3:///[bucket_name]/[dir_path]
- sftp://ftp.snaplogic.com:22/home/test/dir
- ftp://ftp.snaplogic.com/test/csv
- $directory
- _directory (A key-value pair with "directory" key should be defined as a pipeline parameter. Ensure that the '=' button is enabled when using parameters.)
- file:///D:/testFolder/ (if the Snap is executed in the Windows Groundplex and needs to access the D: drive)
- wasb:///Snaplogic/testDir/ or wasbs:///Snaplogic/testDir/
- gs:///testBucket/testDir/

Default value: [None]

The protocol and the rest of the URL should be separated by "://". The host name and the port number should be between "://" and "/".
Not all file protocols support "//", use "///" instead. For example, if polling files in SLDB and S3 (see the examples shown above).
This property should be an absolute path for all protocols except SLDB. For SLDB, the Snap can access only the same project directory or the shared project directory, and cannot access other project directories.
If you want this property to refer to the SLDB project (or shared project) directory where the pipeline of this Snap belongs to, enter "sldb:///" or leave it blank.
If the pipeline is created in a project other than the shared project and you want this property to refer to the shared project, enter "shared" or "sldb:///shared".
If the port number is omitted, a default port for the protocol is used. The hostname and port number are omitted in the SLDB and S3 protocols.

File filter

Required. A GLOB pattern to be applied to select one or more files in the directory. The File filter property can be a JavaScript expression which will be evaluated with values from the input view document.
Example:

*.txt
ab????xx.csv

Default value: [None]

Glob Pattern Interpretation Rules

Use glob patterns in this filter to select one or more files in the directory. For example:

*.java Matches file names ending in .java.
*.* Matches file names containing a dot.
*.{java,class} Matches file names ending with .java or .class.
foo.? Matches file names starting with foo. and a single character extension.

The following rules are used to interpret glob patterns:

The * character matches zero or more characters of a name component without crossing directory boundaries.
The ? character matches exactly one character of a name component.
The backslash character (\) is used to escape characters that would otherwise be interpreted as special characters. For example, the expression \\ matches a single backslash, and "\{" matches a left brace.
The [ ] characters are a bracket expression that match a single character of a name component out of a set of characters. For example, [abc] matches 'a', 'b', or 'c'. The hyphen (-) may be used to specify a range; so, [a-z] specifies a range that matches from 'a' to 'z' (inclusive). These forms can be mixed; so, [abce-g] matches 'a'", 'b', 'c', 'e', 'f' or 'g'. If the character after the '[' is an '!', then it is used for negation; so, [!a-c] matches any character except 'a', 'b', or 'c'.
Within a bracket expression, the *, ?, and \ characters match themselves. The (-) character matches itself if it is the first character within the brackets, or the first character after the '!', if negating.
The { } characters are a group of subpatterns, where the group matches if any subpattern in the group matches. The ',' character is used to separate subpatterns. Groups cannot be nested.
Leading period / dot characters in file names are treated as regular characters in match operations. For example, the '*' glob pattern matches file name '.login'.
Some special characters are not supported. A partial list of unsupported special characters: #, ^, â, ê, î, ç, ¿, SPACE.

Polling interval in seconds

Required. The time-gap between each poll request (in seconds).

Example: 10

Default value: 30

Polling timeout

Required. A period of time after which file polling must end. You specify the number here and the time unit in the next property. Its unit is selected in the next property.

Example:

-1 (to poll indefinitely)
0 (to poll once)
60 (its unit shown in the next property)

Default value: 30

Configure this property based on the expected number of files in the target directory. If there are many files and this property's value is small, the Snap may complete the operation and stop before the file is found.

Polling-timeout unit

Unit for the polling timeout. Allowed values are SECONDS, MINUTES and HOURS.

Example: SECONDS

Default value: MINUTES

Only Output on Change

Select this check box to instruct the Snap to provide an output only when there is a change in the contents of the polled directory. When selected, the Snap provides an output during its initial run if it finds matching documents. However, it provides polling results in the next run only if the polled directory has newer files that match the pattern specified.

Default value: Selected

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

Examples

Writing out the List of Files in a Specific Directory Using the File Poller

In this example, you test the File Poller Snap to see whether it reliably lists out files from a specific directory. You then write the output to a file and run the File Poller Snap again to check whether the new file was created as expected. To ensure that the File Poller Snap doesn't pick up any existing files, you use an unusual extension for this exercise.

Download this pipeline.

Understanding the pipeline

File Poller

You add a File Poller Snap and configure it to poll a directory for all files with the extension ".JSON2":

You then use a combination of JSON Formatter and File Writer Snaps to process the output and write it out to a file. You use the date.now() function to give the file a name, so every time you run the pipeline, a new file is created.

You use the JSON Formatter Snap with the default settings.

File Writer

When used in production, the output from the File Poller Snap can be used to trigger specific tasks as needed. In this example, you write it to a file:

As expected, the file contains no output, as there is no file in the target directory with the extension ".JSON2".

You now add a second File Poller Snap and configure it exactly as you configured the first one. Once again, you add a JSON Formatter and File Writer Snap with the same settings as for the previous pair. But this time, the file created is not blank: It lists out the file that you created using the first three Snaps in the pipeline:

This tells you that the File Poller Snap works as expected with the settings you have used.

Polling a Directory Using a Trigger Task from ServiceNow

In this example, you call a Trigger Task from ServiceNow to poll a directory for files of a specific type.

Download this pipeline

Understanding the pipeline

To make this example work, you must perform the following tasks:

Create a pipeline that receives specifications from ServiceNow on the file type for which you want to poll a directory.
Create a Trigger Task that will make the pipeline available as a REST API.
Create a REST call in ServiceNow that will trigger the Task created in Step 2 above.

Creating the File Poller Pipeline

You design a pipeline containing the following Snaps:

CSV Parser: Parses the data coming in from ServiceNow as a CSV document.
Mapper: Makes the contents of the input CSV document available as a parameter.
File Poller: Polls a specific directory for files matching the pattern specified in the parameter received from the Mapper Snap.

You will note that the File Poller has open input and output views. This is because it receives data from the Trigger Task associated with it and returns processed data back to the same Trigger Task.

CSV Parser

You use the CSV Parser Snap with the default settings:

Mapper

You configure the Mapper Snap to receive the parsed CSV data and map the message in the CSV document to the $msg variable:

File Poller

You configure the File Poller Snap to poll the /QA/Documentation/File Poller/ directory for all files that match the pattern contained in the $msg variable, which you use as a file filter parameter:

Creating a Trigger Task for the File Poller Pipeline

You save the pipeline, click the (Create Task) button, and configure the Trigger Task:

You click Update to complete setting up the task; then navigate to the Manager to view the Trigger Task's properties:

You copy the Cloud URL and authorization bearer token, and navigate to ServiceNow to set up the API call.

Creating a REST call in ServiceNow

Create a REST Call in ServiceNow by appending the authorization token to the Cloud URL that you copied in the previous step:

For details on how to set up REST calls using ServiceNow, see ServiceNow documentation.

While configuring the REST call, ensure that:

HTTP Method is POST.
Endpoint contains the Cloud URL concatenated with the bearer token.
HTTP Parameters > Content contains the variable and extension value that you want to use.

You click Test to check the REST call. For a successful execution, the pipeline returns a list of files whose extension matches the value in the Content field:

Fixed an issue with the File Writer Snap where the Snap fails to connect to the SFTP endpoint using the AWS Transfer Family. Fixed an issue where integration Pipelines fail to connect the SFTP Server with the Binary Snap Pack when upgraded to the SnapLogic 4.25 release version (main9554).
4.25 Patch	425patches10217	23 Jun 2021	Latest	Fixed the following issues in the PGP Decrypt Snap caused due to the Snap patch 425patches9581: The Snap writes an empty document to the output view when there is an error in the Snap. It will now decrypt the document and write it to the output view only if it succeeds. The Snap fails to decrypt any non-signed encrypted file more than 500 bytes. It will now decrypt both non-signed and signed encrypted files. Removed the Project ID field from the Google Service Account, since the JSON Key already contains information about the Project ID.
4.25 Patch	425patches9581	05 May 2021	Latest	Fixed an issue with the PGP Decrypt Snap where the Snap writes an empty document to the output view when there is an error in the Snap. It will now decrypt the document and write it to the output view only if it succeeds. As of 23 Jun 2021 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 Patch	425patches9564	18 Apr 2021	Latest	Enhanced the SFTP session in Binary Snaps to support the SFTP servers which close SFTP sessions slowly.
4.25	main9554	08 May 2021	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.

4.23 Patch	423patches7660	-	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.
4.23	main7430	-	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/zip, application/java-archive and so on; and pass it as the $content-type (case-sensitive) for the file.
