Hi,
I did some further tests, I tried the below code snippet (in remote mode)
after executing alter database custom useLightweightEdges=true from
console.The higlighted line seem to be cause, which is why its ending up
creating the non lightweight edges.
If I set graph.setUseLightweightEdges(true) explicitly before creating the
edges,then it works and i get the lightweigh edges. So I am using this
workaround for the timebeing.
OrientGraphFactory factory = new
OrientGraphFactory("remote:localhost/test1","admin","admin");
factory.setUseLightweightEdges(true);
OrientGraphNoTx graph = factory.getNoTx();
final List<OStorageEntryConfiguration> custom =
(List<OStorageEntryConfiguration>)
graph.getRawGraph().get(ATTRIBUTES.CUSTOM);
for (OStorageEntryConfiguration c : custom) {
if (c.name.equals("useLightweightEdges"))
System.out.println("StorageEntryConfig IsLightweightEdge:" +
Boolean.parseBoolean(c.value)); //prints true which is fine.
}
*System.out.println("Graph IsLightweightEdge:" +
graph.isUseLightweightEdges()); //This prints false which seem to be the
issue*
Thanks
Sajal.
