> There are sometimes many property indexes, therefore cost calculation is slow. As seen
in OAK-4076, we could re-order the indexes and stop once we found a good one (specially for
unique indexes).
> Also, currently we still check if traversal is faster than using an index. In many cases
this check is not needed.
