[jira] [Created] (LUCENE-9350) Don't cache automata on FuzzyQuery

Alan Woodward created LUCENE-9350:
-------------------------------------

             Summary: Don't cache automata on FuzzyQuery
                 Key: LUCENE-9350
                 URL: https://issues.apache.org/jira/browse/LUCENE-9350
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Alan Woodward
            Assignee: Alan Woodward


LUCENE-9068 moved construction of FuzzyQuery's automaton directly onto the query itself.  However, as SOLR-14428 demonstrates, this ends up blowing up query caches that assume query objects are fairly small when calculating their memory usage.  We should move automaton construction back into FuzzyTermsEnum, while keeping as much of the nice refactoring of LUCENE-9068 as possible.
