Notify and Listen

The Notify and Listen components are used together. They pass data through the context of the current graph run. They don't send external notifications or persist data between runs.

Both components are in beta.

Notify component

The Notify component stores input data under a context key and activates Listen components that use the same key. Strings, objects, messages, tables, and data frames are normalized to Data.

Input	Type	Default	Description
Context Key	String	Required	Key used to store and retrieve the data during the graph run.
Input Data	Data, JSON, Message, DataFrame, or Table	Empty	Data to store.
Append	Boolean	false	Add the value to a list under the key instead of replacing the existing value.

The JSON output returns the normalized input data.

Listen component

The Listen component retrieves data stored under its Context Key. The key must exactly match the Notify component's key. If the key has no value, the JSON output returns empty data.

You can pass the output to another component, such as If-Else.
