<p>By default, JDO/DataNucleus supports the concept of <a
href="http://www.datanucleus.org/products/datanucleus/jdo/orm/cascading.html";>persistence-by-reachability</a>.
That is, if
a non-persistent entity is associated with an already-persistent entity, then
DataNucleus will detect this and will automatically persist the associated
object. Put another way: there is no need to call Isis'
<code>DomainObjectContainer#persist(.)</code> or
<code>DomainObjectContainer#persistIfNotAlready(.)</code> methods.</p>

+<p>However, convenient though this feature is, <strong>you may find that it
causes performance issues</strong>.</p>
<p>One scenario in particular where this performance issues can arise is if
your entities implement the <code>java.lang.Comparable</code> interface, and
you have used Isis' <a
href="../../../reference/Utility.html">ObjectContracts</a> utility. The issue
here is that <code>ObjectContracts</code> implementation can cause DataNucleus
to recursively rehydrate a larger number of associated entities. (More detail
below).</p>
