> A Gremlin user let me know about the following issue. If the query below is
> run twice, the name parameter on the 4567 vertex does not get updated. The
> name on the 1234 vertex does get updated. The query is written this way as
> not all databases support single cardinality as the default. The issue has
> been reproduced using both TinkerGraph and Amazon Neptune.

> g.mergeV([(T.id): 'test-test-1234']).
> option(onCreate, [(T.label): 'someLabel', 'name': 'name1']).
> option(onMatch, sideEffect(property(single,"name","name2")).constant([:])).
> mergeV([(T.id): 'test-test-4567']).
