            <title>[SERVER-17892] Explicitly turn checksum on for all collections/indexes in WiredTiger by default</title>
                <link>https://jira.mongodb.org/browse/SERVER-17892</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Enable block checksums even when compression is enabled on all new collections and indices.  Previously, checksum was enabled only on blocks which are not compressed for any reason.&lt;/p&gt;

&lt;p&gt;The performance impact is negligible on most workloads, but can be configured on individual collections and indexes.  WiredTiger documentation for checksum configuration is &lt;a href=&quot;http://source.wiredtiger.com/2.5.2/struct_w_t___s_e_s_s_i_o_n.html#a358ca4141d59c345f401c58501276bbb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;</description>
