Global parameters

Open

Global parameters enable you to define environment variables once and reference them across multiple functions and streams within a single Usage Engine Cloud Edition account. AWS Parameter Store manages these parameters centrally and encrypts values based on the sensitivity level.

A parameter is a named value, such as an API token, URL, or secret, that you can use in configuration fields throughout your streams. By using parameters, you can centrally manage sensitive or environment-specific values, reducing the need to hardcode them in multiple places.

Global parameters offer several key benefits that improve how you manage configuration values across your streams and functions:

• Reusability - Define a parameter once and use it in multiple streams or functions, which promotes consistency and reduces duplication.

• Security - Store sensitive values, such as API tokens and secret IDs, always encrypted.

• Maintainability - When you update a parameter value, all functions referencing it will automatically use the new value on the next stream run, which simplifies maintenance.
