Hi, As David recently ( https://lists.apache.org/thread/xwr8j0ydmxjrq7q74020728jg1bqv2k3) mentioned the ExternalFileField that feature is old and should probably be no longer used. It has no replication support and potential memory leaks (SOLR-10550). I suggest evaluating the In-Place-Updates alternative ( https://solr.apache.org/guide/solr/latest/indexing-guide/partial-document-updates.html#in-place-updates ).
