What type of flow variable is ideal for temporary storage of data?

Local variables are specifically designed for temporary storage of data within the context of a single flow. They exist only during the flow's execution and are used to hold data that is relevant only for that specific instance. Once the flow ends, these variables are cleared and do not retain their values for future executions.

This makes local variables particularly useful for situations where you need to handle data that doesn't need to be stored permanently, such as intermediary calculations or holding data that will be processed immediately. They ensure that data from one execution does not unintentionally affect another, providing a clean workspace.

In contrast, global variables are accessible across multiple flows and maintain their values throughout the lifetime of the app, making them unsuitable for temporary data storage. Static variables are used for maintaining a state or value throughout a session, while persistent variables are designed for storing data that must be retained beyond the flow's execution.
