variant ID
The variantID is a unique string identifier of the variant. This implementation uses random-based UUIDs. This guarantees (to a high probability) that each variant in a distributed system is uniquely identified. The pair of variantID and variantTime result in a sortable unique identifier.
The variantID can safely be used as an access identifier, also in distributed use-cases. This information is stored redundant in Fragment. However, the information stored here are the primary source
