Flow

Description:

This Snap routes binary documents to different output views based on a boolean expression.

A binary document consists of the binary content and a header that contains metadata for that content. For example, a file containing JSON data might have a header with a 'content-type' field set to 'application/json'. This Snap then allows you to separate a single stream of binary documents into multiple streams based on their header data. For example, when unzipping an archive with the ZipFile Read Snap, any files with a "content-type" of "application/json" could be sent to a JSON Parser and "text/xml" files could be sent to an XML Parser. The set of header fields available depends on the Snap that outputs the binary document. You can click on the preview icon for a binary view to see the content and headers that are being generated for each binary document. The following fields are often available:

Name	Example	Description
content-type	application/json	The MIME type for the binary content. If not available from the original source, this value will be derived from the file name.
content-length	1234	The length of the binary content.
content-location	sldb:///test.json	The URL for the original source of the binary stream.
last-modified	2014-07-17T17:12:03.000 UTC	The date that the binary was last modified.

Header fields are not yet available in the schema drop-down for the properties; consult the preview data to see what fields are available.

Prerequisites:

[None]

Support and limitations:

Works in Ultra Tasks.

Account:

Accounts are not used with this Snap.

Views:

Input	This Snap has exactly one binary input view.
Output	This Snap has at least two binary 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.

Routes

Required. Expression to evaluate and output views to write a binary document if the expression evaluates to true. The Expression should be applied to the fields available in binary document header. List of expressions can be seen here .

Example:

$file_name == "File1"
$["content-length"] > 1000
$['content-location'].endsWith("File1")
startsWith($description, "Snap") && $quantity < 100

Default value: [None]

First match

If true (selected), then the first output view whose corresponding expression evaluates to true will only have the binary document written to it even if there are other matches. If false (not selected), then all output views whose corresponding expression evaluates to true will have the binary document written to it.

Example:

Expression | Output View Name
$["content-length"] > 1000 | output1
$["content-length"] <=1000 | output2

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.

Default Value: Execute only
Example: Validate & Execute

Examples

Pipeline Demonstrating the Binary Router Snap

This pipeline demonstrates the Binary Router Snap.

The first Snap reads a JSON document that contains three filenames. The JSON Splitter Snap turns it into three documents and the filename is passed as a parameter to the File Reader Snap. That Snap reads the first file, passes it to the Binary Router Snap where it is evaluated, a new file is written and then the next file is read and the process is repeated.

The evaluation in the Binary Router looks at the content-length and sends it to a different output view depending on size based on the following criteria:

$["content-length"] <= 10
$["content-length"] >= 11 && $["content-length"] <= 1023
$["content-length"] > 1024

Release	Snap Pack Version	Date	Type	Updates
November 2024	main29029	13 Nov 2024	Stable	Updated and certified against the current SnapLogic Platform release.
August 2024	438patches28470	22 Oct 2024	Latest	Added the PipeLoop Snap that enables you to loop on pipeline executions based on a stop condition or iteration limit. The execution workflow of this Snap enables the parent pipeline to control and manage iterative processes using the child pipeline, for scenarios where repeated processing is needed until a specific stop condition is met.
August 2024	438patches28047	16 Sep 2024	Latest	Enhanced the Head and Tail Snaps (for the Number of documents and Document offset fields) to support pipeline parameters via expressions that enable you to reuse the pipelines.
August 2024	main27765	21 Aug 2024	Stable	When the Router Snap was the first Snap in a triggered task, the documents were not processed. Previously, the response contained a `200 status code` but was empty. Now, it processes one document and provides non-empty output. Behavior change: Previously, the Router Snap generated no output without an input document. Now, the Snap generates an empty document when no input document is provided.
May 2024	437patches26857	10 Jul 2024	Latest	Enhanced the Pipeline Execute Snap to support expression values via pipeline parameters for the Batch size field that enables you to use intermediate pipelines for generic use cases.
May 2024	main26341	08 May 2024	Stable	Updated and certified against the current SnapLogic Platform release.
March 2024	436patches25576	19 Mar 2024	Latest	Fixed an issue with the Pipeline Execute Snap where a condition resulted in the output documents not being read.
February 2024	main25112	14 Feb 2024	Stable	Updated and certified against the current SnapLogic Platform release.
November 2023	main23721	08 Nov 2023	Stable	Updated and certified against the current SnapLogic Platform release.

May 2023	433patches22107	08 Aug 2023	Latest	Fixed an issue with the Pipeline Execute Snap that caused it to acknowledge the Ultra pipeline message before the message reached the last Snap in the pipeline. Because of the early acknowledgment, the last Snap in the pipeline failed and the response could not be sent back.
May 2023	433patches21744	28 Jun 2023	Latest	Fixed an issue with the Pipeline Execute Snap where a missing label produced a null pointer exception.
May 2023	433patches21196	25 May 2023	Latest	Fixed an issue with the Pipeline Execute Snap where no input view produced a null pointer exception.

The Pipeline Execute Snap now provides the following capabilities: Specify the Snaplex on which to run child Pipelines. You can now select the Snaplex on which to run the child Pipelines through the Execute On and Snaplex Path fields. The default option is executing the child Pipeline on the same Snaplex node as the Parent, but you can also specify a different Snaplex through the drop-down list, which includes the option to manually enter a Snaplex name. Configure retry logic for child Pipeline executions. You can now configure retry logic for child Pipeline executions though the following fields: Number of Retries, Retry Interval, and Timeout fields.
