> Solr should migrate Lucene's {{LeafReader.storedFields()}} API ([new as of
> Lucene 9.5|https://github.com/apache/lucene/pull/11998]) in place of the
> now-deprecated {{LeafReader.document()}} API (and associated
> {{CloseableThreadLocal}} approach).
> A significant amount of heap space can be retained by the deprecated
> approach, particularly in many-segment, many-thread use cases (look for
> CompressedStoredFieldsReader in heap dumps).
