Unexpected query results with DSE Java Driver

I’m getting unexpected results using the DSE Java Driver with the query below:

List<Object> results = DseGraph.traversal(session).V()
.has("name", "marko").out("knows").values("name")
.toBulkSet().stream().collect(Collectors.toList());

I expected the returned List to contain 2 items of type String in the list being “vadas” and “josh”, But instead it’s returning a list with 2 items of type LinkedHashMap with first item with key as result and the value as vadas and second item as key as result and the value as josh. Any idea why?

Solution

  • Apparently dse-java-driver-core 1.2.3 returns the results in LinkedHashMap. Whereas 1.4.0 returns List of String.
