>
> 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.
