Sequence

Overview

This Snap is used to generate a sequence of numbers. This sequence can start at any positive or negative integer and continue to provide new numbers by adding the step value to the previously generated number.

The Snap does not require any input. However, if input is passed, it generates a sequence where the number of output documents is equal to the number of input documents.
Note: The Snap supports only pipeline parameters.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

  • Stop Pipeline Execution Stops the current pipeline execution when an error occurs.
  • Discard Error Data and Continue Ignores the error, discards that record, and continues with the remaining records.
  • Route Error Data to Error View Routes the error data to an error view without stopping the Snap execution.

Snap settings

Legend:
  • Expression icon (): Allows using 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 more.
  • Suggestion icon (): Populates a list of values dynamically based on your Snap configuration. You can select only one attribute at a time using the icon. Type into the field if it supports a comma-separated list of values.
  • Upload : Uploads files. Learn more.

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: Sequence

Example: Sequence Snap
Initial Value Integer/Expression Required. The initial value of the sequence.
Note: The pipeline should be validated once when the schema file has been uploaded in order for the schema to be visible in the upstream Snap.

Default value: 1

Example:
  • 0
  • _initial value
Step Value Integer/Expression Required. This property increments (or decrements if negative) the sequence value by this amount to produce the next sequence value.

Default value: 1

Example: -1, 1, _stepvalue
Number of documents Integer/Expression Required. The number of documents to generate.

Default value: 1

Example:

Example: 10, _numberOf Documents

Note: The value in this property is ignored if an input dataset is provided to the Snap. In such cases, the number of documents in the output is equal to the number of documents in the input.
Pass through Checkbox Set this option to determine if input data should be passed through or not.

Default status: Deselected
Snap execution Dropdown list
Choose 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: Validate & Execute

Example: Execute only
