<h1 align=center>Page fill factor (h_ffactor)</h1>
<p>
The desired density within the hash table can be specified as part of the
<a href="../../api_c/Db/open.html">db_open</a> call to open the database, specifically by setting the
<a href="../../api_c/DbInfo/info.html#h_ffactor">h_ffactor</a> element of the DB_INFO structure. If no density
is specified, one will be selected dynamically as pages are filled.
