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. 

The Snap supports only pipeline parameters.

Input and Output

  • Expected input: Optional. A document containing the initial value of the sequence and the increment value that you want to use to create the sequence.

  • Expected output: A document containing the sequence generated using the input parameters.

  • Expected upstream Snaps: Any Snap that offers documents. For example, JSON Parser, JSON Splitter, or Mapper.

  • Expected downstream Snaps: Any Snap that accepts documents. For example, Join, or a combination of JSON Formatter and File Writer.

Prerequisites

None.

Snap Settings

Label

Required. The name for the Snap. Modify this to be more specific, especially if there are more than one of the same Snap in the pipeline.

Initial value

Required. The initial value of the sequence.

Example: 

  • 0

  • _initialValue

Default value: 1

Step value

Required. This property increments (or decrements if negative) the sequence value by this amount to produce the next sequence value.
Example: 

  • -1 (negative value)

  • 1 (positive value)

  • _stepValue

Default value: 1

Number of documents

Required. The number of documents to generate.
Example: 

  • 10

  • _numberOfDocuments

Default value:  1

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

Set this option to determine if input data should be passed through or not.

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
