Workflow-specific settings can be stored in environment variables. Since you can have multiple workflows using the same application, environment variables are great for storing values that are specific to a workflow (E.g. cluster names, specific queries, service names, IDs).
Environment variables are stored encrypted-at-rest.
You can define an environment variable schema at Settings > App Info > Environment variables schema. Environment variables values are set when you create a workflow.
Environment variable names must be strings (case-sensitive), with the following restrictions:
Environment variable values can be any valid string, number, or boolean. There are no length or character restrictions. If left blank, they will default to
Here is how you can access the environment variables for a workflow in your code:
// => "stringValue"
// => 88888
// => True
// => null
// => exception
Please see the Python operation documentation for information on programmatically accessing environment variables.
