SnapLogic Snaps are modular collections of integration components built for specific applications or data sources. Snaps aid both business users and developers from having to handle much of the complexities in the underlying application, data model, and service.
SnapLogic includes the following basic types of Snaps with distinct icons.
Specifies data sources in the Pipeline.
Examples: File Reader, CSV Generator, Query
Takes the input of unstructured data and generates an output of structured data.
Examples: XML Parser, Sequence Parser, JSON Parser
Modifies data significantly.
Examples: Mapper, Aggregate, Join
Changes the output or direction of data in a Pipeline.
Examples: Router, Shuffle, Union
Changes the data format.
Examples: CSV Formatter, JSON Formatter, Excel Formatter
Specifies data destinations in a Pipeline.
Examples: Filer Writer, REST Post, Email Delete
Snaps Connect to Build a Pipeline
The key to creating a Pipeline in SnapLogic is connecting Snaps. There are a few things to consider when placing Snaps in a Pipeline.
Like puzzle pieces, only Snaps with matching connection pairs (circles or diamonds) can be connected. Circle connections indicate document data while diamond connections indicate binary data.
|Connection mismatch||Connection match|
When moved to the Pipeline canvas, Snaps may display with an input (the head of the Snap) and output (the tail of the Snap). To modify the input/output properties, click on the Snap and select the Views tab. See Snap Reference for more information on Views.
Disconnect Linked Snaps
Unlinked Snaps can be moved apart or placed next to each other. Make sure the circle or diamond connector is colored blue, which indicates that the Snaps are linked.
|Linked connection||Unlinked connection|
To disconnect linked Snaps, click on the blue connector. This clears the color and allows you to
Go To Links
You can also connect to Snaps that are not next to each other by using a Go To link.
Click and hold on the male connector until it highlights yellow, then drag it to the female connector. When both connections turn blue, release the mouse button. A number is placed in both connectors to let you know they are connected.
The number is only temporary until the Pipeline is saved, at which point a new, permanent number may be assigned to it.
You can also click an
Refer to the video for details.
The right-click menu displays options available in all Snaps through a dropdown list.
The following rules apply to rotation:
- If a Snap is not connected to another Snap, you can rotate the whole Snap or just the head or tail ends. Snaps with multiple inputs or outputs can only be rotated as a whole.
- If the Snap is connected at the head, you can rotate the tail; if connected at the tail, you can rotate the head.
- If a Snap is connected on both ends, it cannot be rotated.
If a Pipeline contains a Snap that is no longer available from the catalog, that Snap is shown in the Pipeline with the central shape colored red.
When a Snap is no longer available, the schema for that Snap is not available to provide specific details for the infobox, so field labels do not display in a user-readable format.
