Honestly, I have no idea which is "old". The solr source itself uses slice pretty consistently, so I stuck with that when I started the project last year. And logically, a shard being an instance of a slice makes sense to me. But one significant place where they word shard is exposed is the default names of the slices, so it’s a mixed bag.
