The <code class="methodname">DB_MPOOLFILE->get_priority()</code> method returns the cache priority for
|
||
the file referenced by the <a class="link" href="memp.html" title="Chapter 8. The DB_MPOOLFILE Handle">DB_MPOOLFILE</a>
|

handle. The priority of a page biases the replacement algorithm to be
|

more or less likely to discard a page when space is needed in the
|

cache. This value is set using the
