            <title>[SERVER-56508] Ability to customize Zstandard compression level</title>
                <link>https://jira.mongodb.org/browse/SERVER-56508</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;At the moment, the compression level for zstd is hardcoded to 6.&lt;/p&gt;

&lt;p&gt;This work is to allow customers to tune the compression level for zstd through configuration.&#160;&lt;/p&gt;

&lt;p&gt;Configuring the compression level for zstd is independent of whether zstd is configured as default log compressor or default block compressor.&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;</description>

                            <comment id="3880989" author="louis.williams" created="Wed, 16 Jun 2021 13:20:17 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=vamsi.krishna&quot; class=&quot;user-hover&quot; rel=&quot;vamsi.krishna&quot;&gt;vamsi.krishna&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=brian.lane&quot; class=&quot;user-hover&quot; rel=&quot;brian.lane&quot;&gt;brian.lane&lt;/a&gt;, why are we prohibiting the use of negative compression levels for zstd? From &lt;a href=&quot;https://facebook.github.io/zstd/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://facebook.github.io/zstd/&lt;/a&gt;&lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above.&lt;/p&gt;&lt;/blockquote&gt;</comment>
