[jira] [Created] (LUCENE-9955) Remove state from stored fields readers

Adrien Grand created LUCENE-9955:
------------------------------------

             Summary: Remove state from stored fields readers
                 Key: LUCENE-9955
                 URL: https://issues.apache.org/jira/browse/LUCENE-9955
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand


Because stored fields readers are cached per-segment per-thread, they can quickly start using lots of memory. E.g. an innocent 10kB buffer with 10 Lucene indices that have 100 segments each and are queried by 100 threads would eventually end up using 1GB of heap.
