What is the purpose of

tag

in the flytekit.models

Binary

literal?

class Binary(_common.FlyteIdlEntity):
    def __init__(self, value, tag):
        """
        :param bytes value:
        :param Text tag:
        """
        self._value = value
        self._tag = tag

Idea was to keep things like the protobuf message name etc in it

For context am writing a TypeTransformer where for certain reasons we want to pickle a dataclass rather than serializing it to JSON and was curious what to specify for that value

So yes you can keep any meta information as it will be used by the compiler to statically verify

Cool, that's what I figured, thanks @Ketan (kumare3). Will use the fully-qualified class name as the tag.
