    Description

      In the case of fullCopy=true, all files are copied over from the leader/master irrespective of whether or not that exact file exists with the replica/slave. This is wasteful, esp. in tlog replicas or pull replicas, when only a fraction of the total files are different.

      This stems from SOLR-11815.
