            <title>[KAFKA-42] how to handle non-JSON format messages when streaming data from Kafka to Mongo</title>
                <link>https://jira.mongodb.org/browse/KAFKA-42</link>
                <project id="16285" key="KAFKA">Kafka Connector</project>
                    <description>&lt;p&gt;Hi team,&lt;/p&gt;

&lt;p&gt;I can stream data from Kafka to MongoDB with JSON messages&lt;/p&gt;

&lt;p&gt;However, if I send a non-JSON format message the Connector died. Please see the log file for details.&lt;/p&gt;

&lt;p&gt;My config file:&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;
&lt;p/&gt;

&lt;p/&gt;
&lt;p&gt;I have 2 separated questions:&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;how to ignore the message which is non-json format?&lt;/li&gt;
&lt;/ol&gt;


&lt;ol&gt;
	&lt;li&gt;how to defined a default-key for this kind of message (for example:&#160;&lt;tt&gt;abc&lt;/tt&gt;&#160;-&amp;gt;&#160;{{
{ &quot;non-json&quot;: &quot;abc&quot; }
&lt;p&gt;}}&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Thanks&lt;/p&gt;</description>

&lt;p&gt;Thank for your response.&lt;br/&gt;
 I am sorry because I didn&apos;t aware that where the problem come from, I thought it was from&#160;MongoDB Sink Connector. So, I could fix it by a proper configuration.&lt;/p&gt;

&lt;p&gt;I raised this on stackoverflow already. But, so far, there is no answer.&lt;/p&gt;

&lt;p&gt;I will reach to Kafka mailing list as you mentioned.&lt;/p&gt;

&lt;p&gt;Thank you again.&lt;/p&gt;

&lt;p&gt;Vu Le&lt;/p&gt;</comment>
                            <comment id="2319122" author="ross@10gen.com" created="Wed, 10 Jul 2019 08:40:06 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=leanhvu1989&quot; class=&quot;user-hover&quot; rel=&quot;leanhvu1989&quot;&gt;leanhvu1989&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;Thanks for the ticket. It seems its Kafka connect that is throwing the error before anything is handled by the MongoDB Sink Connector. As such there is nothing the connector itself can do.&lt;/p&gt;

&lt;p&gt;Just for future reference the best place for questions regarding MongoDB usage or Kafka connector specifics is the &lt;a href=&quot;https://groups.google.com/forum/#!forum/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user mailinglist&lt;/a&gt; or &lt;a href=&quot;http://stackoverflow.com/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;stackoverflow&lt;/a&gt; as you will reach a broader audience there. If your business requires an answer from MongoDB within a time frame then we do offer &lt;a href=&quot;https://www.mongodb.com/products/production-support&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;production support&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;In this case I think using Kafka&apos;s own &lt;a href=&quot;https://kafka.apache.org/contact&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mailing list&lt;/a&gt; may be the be best way to get insight into how best to handle this scenario.&lt;/p&gt;

&lt;p&gt;All the best,&lt;/p&gt;

&lt;p&gt;Ross&lt;/p&gt;</comment>
