Subject [jira] Created: (JDO-405) recursion-depth - fetching the whole graph with 0 or -1?

recursion-depth - fetching the whole graph with 0 or -1?
--------------------------------------------------------

                 Key: JDO-405
                 URL: http://issues.apache.org/jira/browse/JDO-405
             Project: JDO
          Issue Type: Bug
    Affects Versions: JDO 2 final
            Reporter: Ilan Kirsh


In page 124: "A value of -1 means that the recursion-depth is not limited by traversing this
field."
In page 127: "A recursion-depth of 0 will fetch the whole graph of instances reachable from
this field"

Is there a difference between these two?

In addition, I think that -1 / 0 as a default might be better than 1 it terms of performance,
because tracking such cycles has some overhead, which we might not want to pay for most fields
in which this feature is not needed (and MaxFetchDepth is sufficient).
