Re: using uuid for documents

[Zahra Aminolroaya]

Hello Alfonso,

I expected that we could use *uuid* updateRequestProcessorChain like below
for generating unique value for unique key:


 
uniqueKey 




However, I saw that you used *dedupe* updateRequestProcessorChain as below;

 
 
  true 
………

I wonder if we can use *UUIDUpdateProcessorFactory* class instead of
*SignatureUpdateProcessorFactory* class!

Hi Zahra,

I’m not sure I understand your question. Could you explain with more detail 
what it is that you want to achieve?

Hello Alfonso,


Thanks. You used the dedupe updateRequestProcessorChain, so for this
application we cannot use the uuid updateRequestProcessorChain
individually?!


Best,
Zahra

Re: using uuid for documents

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).
  

  true
  id
  false
  bioentity_identifier,property_name,property_value
  solr.processor.Lookup3Signature



  




  

As for your second question, how is that different to automatic UUID generation?

HTH,

Alfonso
