<h1 align=center>Release 3.1: identical duplicate data items</h1>
|
|
<p>In previous releases of Berkeley DB, it was not an error to store identical
|
|
duplicate data items, or, for those that just like the way it sounds,
|
|
duplicate duplicates. However, there were implementation bugs where
|
|
storing duplicate duplicates could cause database corruption.
|
|
<p>In this release, applications may store identical duplicate data items
|
|
as long as the data items are unsorted. It is an error to attempt to
|
|
store identical duplicate data items when duplicates are being stored
|
|
in a sorted order. This restriction is expected to be lifted in a future
|
|
release. See <a href="../../ref/am_conf/dup.html">Duplicate data items</a>
|
|
for more information.
