Heyhey, With this query I'm able to get only the RIDs of the linked vertices going around the RID Bag limits, but I still need to fetch linked vertex with another query later. I would have thought that, since there is an expand(in(...)) it would have returned the vertices and not their RIDs only

[orientdb] Re: OrientDB 3.0 will run on Java8 only?

The only negative consequence of an update to Java 8 that I can see is that OrientDB will no longer be a viable option in environments which tend to adapt slowly to new technology, i.e. environments where Java 7 or older is still up and running. This affects mostly enterprise areas, I think for

I have created a database with two vertices in it. *Stores*, *Products*. Stores have a *GeoSpatial Index*. There is an Edge '*hasInventory*' from store to products which holds quantity for each Product-Store relation. Now If I have to find a particular Product(sku) in near by stores how should I
