Hello, I have a single node Solr 6.4 server, with a Index of 100 Million documents. The default "id" is the primary key of this index. Now, I would like to setup an update process to insert new documents, and update existing documents based on availability of value in another field (say ProductId), that is different from the default "id". Now, to ensure that I use the Solr provided De-Duplication method by having a new field SignatureField using the ProductId as UniqueKey. Considering the millions of documents I have, I would like to ask if its possible to setup a De-Duplication mechanism in an existing solr index with the following steps:
a. Add new field SignatureField, and configure it as UniqueKey in Solr schema. b. Run an Atomic Update process on all documents, to update the value of this new field SignatureField. Is there an easier/better way to add a SignatureField to an existing large index? Thx, Pankaj
