Craig Russell updated JDO-405:
------------------------------
Fix Version/s: JDO 2 maintenance release 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
> Fix For: JDO 2 maintenance release 1
>
>
> 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).
