Yes, I am convinced of this statement. I was asking myself two important
modelling questions, which are not as trivial as I expected.
First of all: in general are lightweight edges faster than regular edges
without properties? Benchmark answer is NO (for Orient >= 2.0.0).
Second. if most of my queries involve typed edges (e.g. SELECT FROM V WHERE
out('type1').size() > 0) it is most efficient:
- create many subclasses of E (and maybe indexing the property E.@CLASS)
- create a property E.type and then a index over it
Anyway your suggestions were precious. I also discovered your very
interesting project for OrienDB benchmarking: I'm definitely interested in
looking into your use cases and maybe providing new ones.
Cheers,
Riccardo
