-------------------------------------
Summary: Update Solr to use new Lucene 9.5 storedFields() API
Key: SOLR-16677
URL: https://issues.apache.org/jira/browse/SOLR-16677
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Michael Gibney
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).
