            <title>[SERVER-75722] Avoid memory copies on gRPC&apos;s read path</title>
                <link>https://jira.mongodb.org/browse/SERVER-75722</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We use a custom memory layout for our &lt;tt&gt;SharedBuffer&lt;/tt&gt; objects, which reserve a few bytes at the beginning of each contiguous memory region for metadata (e.g., the capacity of the buffer). As a result, we cannot have &lt;tt&gt;SharedBuffer&lt;/tt&gt; own the memory allocated by gRPC to read from a server stream. This requires an additional heap allocation and memory copy on the critical path.&lt;/p&gt;

&lt;p&gt;We can avoid the copy by either changing the layout of the byte-array sent through gRPC streams, or modify &lt;tt&gt;SharedBuffer&lt;/tt&gt; to accepts raw buffers. &lt;/p&gt;</description>
