It's easy to add more storage capacity to a Class by simple creating and adding a new Cluster to that Class. There is also a way to remove a Cluster from a Class, but this doesn't "redistribute" the data in that Cluster to other Clusters in the Class. Is that function supported "automatically" (i.e. in any way other than to write code to scan through the RIDs in the removed Class and create new records in one of the remaining classes)?

Hi Eric,

Moving records from a cluster to another is not supported, because re-calculating link references is a very expensive operation.
There is a MOVE VERTEX command that (as you can guess) is specific to vertices, it takes into consideration edges and re-attaches them correctly

Thanks

Luigi
