Data jobs support properties stored in Control Service API by default (plugins can extend this). Job properties serve to:

• store credentials securely
• store Data Job state
• store job deployment configuration

The IProperties interface in JobInput is used to manipulate the properties.

To be able to use Data Jobs properties, You can then manipulate the properties using a code like this one:

def run(job_input: IJobInput):
    properties = job_input.get_all_properties()
    properties["db_pass"] = "the password goes here"
    job_input.set_all_properties(properties)

or using CLI

vdk properties --help
