            <title>[KAFKA-75] New id strategy that doesn&apos;t reuse configuration parameters. </title>
                <link>https://jira.mongodb.org/browse/KAFKA-75</link>
                <project id="16285" key="KAFKA">Kafka Connector</project>
                    <description>&lt;p&gt;We want to support a solution to config more than one processor on the chain of post processors.&lt;/p&gt;

&lt;p&gt;Consider the following example:&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;  &quot;topic.override.source.document.id.strategy&quot;:&quot;com.mongodb.kafka.connect.sink.processor.id.strategy.PartialValueStrategy&quot;,&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;     &quot;topic.override.source.collection&quot;:&quot;sink&quot;,&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;

			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Currently, this fails to update correctly the MongoDB documents. The current design only allows one processor to be configured as it is not possible to configure settings for each of the processors.&lt;/p&gt;

&lt;p&gt;This work is to implement a new id strategy that does not reuse configuration parameters.&lt;/p&gt;</description>

&lt;p&gt;Message: Add specific configurations for Partial&lt;span class=&quot;error&quot;&gt;&amp;#91;Key|Value&amp;#93;&lt;/span&gt;Strategies&lt;/p&gt;

&lt;p&gt;Added `document.id.strategy.partial.key.` configurations and&lt;br/&gt;
`document.id.strategy.partial.value.` configurations.&lt;/p&gt;

&lt;p&gt;So that users can both project fields as part of the Id Strategy&lt;br/&gt;
as well as project any fields they want to store.&lt;/p&gt;

&lt;p&gt;There is nothing stopping custom processors using their own parameters, its just you can&apos;t double define the projection configuration for the &lt;tt&gt;PartialValueStrategy&lt;/tt&gt; and also use them for the &lt;tt&gt;WhitelistValueProjector&lt;/tt&gt;.  I believe the current workaround would be to use SMT (Single Message Transformations) that are native to Kafka to process the data first and project the required fields.&lt;/p&gt;

&lt;p&gt;Future work should use a name based convention for configuration for the Id strategies.  Keeping backwards compatibility may be a challenge.&lt;/p&gt;</comment>

`document.id.strategy.partial.key.projection.type` and `document.id.strategy.partial.key.projection.list`.&lt;/p&gt;
