Variables

Variables act as shared, in-memory storage at the board level. Typical scenarios for using variables include:

• Configuring the name of a database and reusing it across multiple flows (e.g., for ingestion and retrieval).
• Recursively scraping a website for outgoing links and pushing each link into an array.
• During each While Loop iteration, evaluating whether a certain condition is still true. The condition is set somewhere downstream in the While Loop leaf branch.

All flows within a board can read and write variables through the Get Variable and Set Variable nodes:

• To read a variable, either search the node catalog for Get variable_name or drag and drop the variable from the variables menu onto the canvas.
• To write a variable, either search for Set variable_name or drag it from the variables menu.

To specify a variable type, open the variables menu, click the variable you want to configure, and select the type from the drop-down list:

To specify a variable value (Single, Array, Set, or Map), click the pill-shaped color indicator next to Variable Types:
