> There is a race condition that causes duplication of schema vertices as a result of concurrent
graph updates. This in turn leads to failure of queries that specify a type such as an edge
label used in an attribute that references another entity. This problem is known to affect
Atlas entity refs – which create graph edges that use edge label schema vertices. It is
likely that it also affects other types in Atlas.
