<p>As you probably know, the replication in couchdb is triggered by sending a <span class="caps">JSON</span> doc to the <code>_replicate</code> <span class="caps">URL</span> using a <span class="caps">POST</span> request. Something like that:</p>
<div class="highlight pygments-style-monokai rounded shadow-sm mb-3"><pre><span></span><code><span class="go">curl -X POST http://localhost:5984/_replicate -d '{source:http://src_ip:5984/src_db, target:dst_db, continuous:true}' -H 'Content-Type: application/json'</span>
</code></pre></div>
<p>The problem using this approach is that the replication process does not continue after a CouchDB restart. Since CouchDB 1.1.0, you can use the <code>_replicator</code> database to ensure that the replication processes are triggered again after a service restart. Just fill up the <code>_replicator</code> database with a documment defining the replication process in the same way that you did using the <code>_replicate</code> <span class="caps">API</span>.</p>
<div class="highlight pygments-style-monokai rounded shadow-sm mb-3"><pre><span></span><code><span class="go">curl -X POST -d '{source:http://src_ip:5984/source_db, target:dst_db, continuous:true}' -H 'Content-Type: application/json' http://localhost:5984/_replicator</span>
</code></pre></div>
<p>Now you don’t need to worry about the replication processes after a service restart.</p>
