<h2 id="specific-connection-configuration">Specific connection configuration</h2>
<p>The common configuration for connections in <a href="basic-connections.html#sources">Connections &gt; Sources</a> and
<a href="basic-connections.html#targets">Connections &gt; Targets</a> applies here as well.
Following are some specifics for AMQP 1.0 connections:</p>
<h3 id="source-format">Source format</h3>
<p>Any <code class="highlighter-rouge">source</code> item defines an <code class="highlighter-rouge">addresses</code> array of source identifiers (e.g. Eclipse Hono’s
Telemetry API) to consume messages from
and <code class="highlighter-rouge">authorizationContext</code> array that contains the authorization subjects in whose context
inbound messages are processed. These subjects may contain placeholders, see
<a href="basic-connections.html#placeholder-for-source-authorization-subjects">placeholders</a> section for more information.</p>
<div class="language-json highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="p">{</span><span class="w">
</span><span class="s2">"addresses"</span><span class="p">:</span><span class="w"> </span><span class="p">[</span><span class="w">
</span><span class="s2">"&lt;source&gt;"</span><span class="p">,</span><span class="w">
</span><span class="s2">"..."</span><span class="w">
</span><span class="p">],</span><span class="w">
</span><span class="s2">"authorizationContext"</span><span class="p">:</span><span class="w"> </span><span class="p">[</span><span class="s2">"ditto:inbound-auth-subject"</span><span class="p">,</span><span class="w"> </span><span class="s2">"..."</span><span class="p">]</span><span class="w">
</span><span class="p">}</span><span class="w">
</span></code></pre></div></div>
<h3 id="target-format">Target format</h3>
<p>An AMQP 1.0 connection requires the protocol configuration target object to have an <code class="highlighter-rouge">address</code> property with a source
identifier. The target address may contain placeholders; see
<a href="basic-connections.html#placeholder-for-target-addresses">placeholders</a> section for more
information.</p>
<p>Target addresses for AMQP 1.0 are by default handled as AMQP 1.0 “queues”. There is however the possibility to also
configure AMQP 1.0 “topics” as well. In order to be more specific, the following formats for the <code class="highlighter-rouge">address</code> are
supported:</p>
<ul>
<li><code class="highlighter-rouge">the-queue-name</code> (when configuring w/o prefix, the <code class="highlighter-rouge">address</code> is handled as “queue”)</li>
<li><code class="highlighter-rouge">queue://the-queue-name</code></li>
<li><code class="highlighter-rouge">topic://the-topic-name</code></li>
</ul>
<p>Further, <code class="highlighter-rouge">"topics"</code> is a list of strings, each list entry representing a subscription of
<a href="protocol-specification-topic.html">Ditto protocol topics</a>, see
<a href="basic-connections.html#target-topics-and-filtering">target topics and filtering</a> for more information on that.</p>
<p>Outbound messages are published to the configured target address if one of the subjects in <code class="highlighter-rouge">"authorizationContext"</code>
has READ permission on the Thing, that is associated with a message.</p>

<h3 id="specific-configuration-properties">Specific configuration properties</h3>
<p>The specific configuration properties are interpreted as
<a href="https://qpid.apache.org/releases/qpid-jms-0.40.0/docs/index.html#jms-configuration-options">JMS Configuration options</a>.
Use these to customize and tweak your connection as needed.</p>
<h2 id="establishing-connecting-to-an-amqp-10-endpoint">Establishing connecting to an AMQP 1.0 endpoint</h2>
<p>Ditto’s <a href="architecture-services-connectivity.html">Connectivity service</a> is responsible for creating new and managing
existing connections.</p>
<p>This can be done dynamically at runtime without the need to restart any microservice using a
<a href="installation-operating.html#devops-commands">Ditto DevOps command</a>.</p>
