> SOLR-9269 introduced a mechanism to create/delete snapshots for a Solr core
> (using Lucene IndexDeletionPolicy). The current snapshot cleanup mechanism is
> based on reference counting the index files shared between multiple segments.
> Since this mechanism completely skips the Lucene APIs, it is not portable
> (e.g. it doesn't work on 4.10.3 version).
> I propose an alternative implementation which relies exclusively on Lucene
> IndexWriter (+ IndexDeletionPolicy) for cleanup.
