This Snap routes documents to output views matching a boolean expression. If no expressions are specified, documents will be evenly distributed across all output views.  Multiple views are added to the router through the Views tab. When entering in an output view name and clicking Apply Changes, output view links will be attached to the router in order they are declared. Â
Router vs. Filter
The Router and Filter Snaps are similar, but the Filter Snap only handles a single stream. The Router Snap is designed to handle multiple output views.Â
Previously, the Router Snap generated no output without an input document; now, the Snap generates an empty document when no input document is provided.
This Snap has at least two document output views.
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 Â
Expression to evaluate and output views to write a document if the expression evaluates to true. The list of expressions can be seen here.
When there are no routes defined, this Snap will be in auto-routing mode. In this mode, this Snap works like a load balancer; incoming documents will be forked evenly across all output views, in an alphabetically-ordered, round-robin fashion. Note: If ANY route contains an expression, then only those with expressions are evaluated; those routes without an expression will evaluate to false.
If true, then the first output view whose corresponding expression evaluates to true will only have the document written to it even if there are other matches. If false, then all output views whose corresponding expression evaluates to true will have the document written to it. Example:Â
Expression | OutputView Name
$quantity > 10 | output1
$quantity <=10 | output2Â
Default value: [None]
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.
