-----------------------------------------
Summary: Test + ref-guide note about "safe" way to de-duplicate
documents in SolrCloud
Key: SOLR-15291
URL: https://issues.apache.org/jira/browse/SOLR-15291
Project: Solr
Issue Type: Sub-task
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Chris M. Hostetter
Assignee: Chris M. Hostetter
* The only "safe" way to use SignatureUpdateProcessorFactory for de-duplication
in SolrCloud is to define the {{signatureField}} to be the same as the unique
key field -- ie: let SignatureUpdateProcessorFactory generate the 'id' for each
document
** We should add a note about this to the ref-guide ASAP for inclusion in the
next release
* There are currently no "cloud" based tests of SignatureUpdateProcessorFactory
showing that even this usage works
** We should add a basic test of this usage ASAP to future-proof against it
breaking
