Hello,
I'm using Solr 5.2.1 and Zookeeper 3.4.6. I'm implementing two collections - HotDocuments and ColdDocuments . New documents will only be written to HotDocuments and every night I will migrate a chunk of documents into ColdDocuments. In the test environment, I have the Collection API migrate statement working fine. I know this won't handle duplicates ending up in the ColdDocuments collection and I don't expect to have duplicate documents but I would like to protect against it- just in case. We have a unique key and I've tried to implement de-duplication (https://cwiki.apache.org/confluence/display/solr/De-Duplication) but I still end up with duplicates in the ColdDocuments collection. Does anyone have any suggestions on how I can protect against duplicates with the migrate statement? Any ideas would be greatly appreciated. Many thanks Philippa
