>                 Key: SOLR-16677
>                 URL: https://issues.apache.org/jira/browse/SOLR-16677
>             Project: Solr
>          Issue Type: Improvement
>            Reporter: Michael Gibney
>            Priority: Major
>
> 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).
