Does anyone know how: stdIn=io.airbyte.config.ResourceRequirements can be set by the user? Same for stdOut and heartbeat thanks

You should be able to update them for source definition or destination definition via the

/source_definition/update

or

/destination_definition/update

config-api endpoint or for a connection via

/connection/update

in general check the api spec for

resourceRequirements

properties on update endpoints
