Solr had a "blob store", based on the ".system" collection. I'm not sure if these are effectively the same thing or separated. Any way, "blob store" was deprecated in 9 and removed in 10: SOLR-17284
I'd like to propose the deprecation of the ".system" collection, which I think has a suitable replacement -- the file-store (same thing that replaced the "blob store"). AFAIK, Solr internally only uses this collection for the "schema designer", which could switch to it. ~ David Smiley Apache Lucene/Solr Search Developer http://www.linkedin.com/in/davidwsmiley
