<p>The federation section defines some sub-options related to federation.</p>
<p>The following options are related to configuring timeout and retry logic for one request,
independently of the others.
Short retry algorithm is used when something or someone will wait for the request to have an
answer, while long retry is used for requests that happen in the background,
like sending a federation transaction.</p>
<ul>
<li><code>client_timeout</code>: timeout for the federation requests in seconds. Default to 60s.</li>
<li><code>max_short_retry_delay</code>: maximum delay to be used for the short retry algo in seconds. Default to 2s.</li>
<li><code>max_long_retry_delay</code>: maximum delay to be used for the short retry algo in seconds. Default to 60s.</li>
<li><code>max_short_retries</code>: maximum number of retries for the short retry algo. Default to 3 attempts.</li>
<li><code>max_long_retries</code>: maximum number of retries for the long retry algo. Default to 10 attempts.</li>
</ul>
<p>Example configuration:</p>
<pre><code class="language-yaml">federation:
client_timeout: 180
max_short_retry_delay: 7
max_long_retry_delay: 100
max_short_retries: 5
max_long_retries: 20

<p>Still, it's probably worth investigating why we're getting users from the database that often, and whether it's possible to reduce the amount of queries we make by adjusting our cache factor(s).</p>
<p>The <code>persist_events</code> transaction is responsible for saving new room events to the Synapse database, so can often show a high transaction duration.</p>

<p>The charts in the &quot;Federation&quot; section show information about incoming and outgoing federation requests. Federation data can be divided into two basic types:</p>
<ul>
<li>PDU (Persistent Data Unit) - room events: messages, state events (join/leave), etc. These are permanently stored in the database.</li>
