Hi Zahra,
We had a similar issue in our collections and we solved this by generating a
UUID value using the content of other fields, in reply to your first question.
Have a look at the section
https://lucene.apache.org/solr/guide/7_4/update-request-processors.html#custom-update-request-processor-chain,
specifically at how SignatureUpdateProcessorFactory is used.
In our case, we create a UUID in field “id” (signatureField) from the fields
bioentity_identifier, property_name and property_value (fields).
<updateRequestProcessorChain name="dedupe" default="true">
<processor class="solr.processor.SignatureUpdateProcessorFactory">
<bool name="enabled">true</bool>
<str name="signatureField">id</str>
<bool name="overwriteDupes">false</bool>
<str name="fields">bioentity_identifier,property_name,property_value</str>
<str name="signatureClass">solr.processor.Lookup3Signature</str>
</processor>
<!-- Uncomment to disable explicit commit and optimize calls -->
<!--<processor class="solr.IgnoreCommitOptimizeUpdateProcessorFactory">-->
<!--<int name="statusCode">200</int>-->
<!--</processor>-->
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.DistributedUpdateProcessorFactory"/>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
As for your second question, how is that different to automatic UUID generation?
HTH,
Alfonso
