> * 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
