Feature Synthesis
Overview
The Feature Synthesis Snap generates new features for a base or primary dataset by joining it with other datasets (reference datasets) linked together by common identifiers. Using this Snap, you can view statistical data of all related datasets in the base dataset itself. Some of the generated features include:
- Mean (Numeric data)
- Min (Numeric data)
- Max (Numeric data)
- Mode (Categorical data)
- Unique (Categorical data)
- Count (Generated at the base dataset level)
Transform-type Snap

Snap views
| View | Description | Examples of upstream and downstream Snaps |
|---|---|---|
| Input | This Snap has at least two document input views. The first view is the base dataset, and subsequent views are for reference datasets. | |
| Output | This Snap has exactly one document output view. It outputs the base dataset containing features generated based on the reference datasets. | |
| Error | This Snap has at most one document error view. It captures errors encountered during processing. |
Snap settings
- Expression icon (
): JavaScript
syntax to access SnapLogic Expressions to set field values dynamically (if enabled). If
disabled, you can provide a static value. Learn more. - SnapGPT (
): Generates SnapLogic Expressions
based on natural language using SnapGPT. Learn

| Field / field set | Type | Description |
|---|---|---|
| Label | String |
Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline. Default value: Feature Synthesis Example: |
| Base View | String |
The input view to which the base dataset is connected. Default value: Feature Synthesis Example: |
| Base Path | String |
The field in the base dataset used as the common identifier for joining with the reference dataset. Default value: Feature Synthesis Example: |
| Ref View | String |
The input view where the reference dataset is connected. Default value: Feature Synthesis Example: |
| Ref Path | String |
The field in the reference dataset with the same values as in the base field. Default value: Feature Synthesis Example: |
| Snap execution | Dropdown list |
Select one of the three modes in which the Snap executes.
Available options are:
Default value: Validate & execute Example: Execute only |
