             Summary: Can we remove the FST cache in Kuromoji and Nori analyzers?
                 Key: LUCENE-9064
                 URL: https://issues.apache.org/jira/browse/LUCENE-9064
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Bruno Roustant


Is the ~30k han cache in kuromoji redundant after LUCENE-8920?

[https://github.com/apache/lucene-solr/blob/813ca77250db29116812bc949e2a466a70f969a3/lucene/analysis/kuromoji/src/java/org/apache/lucene/analysis/ja/dict/TokenInfoFST.java#L35-L38])

The entire linked file's purpose is all around this caching, so if its not needed anymore it would be a nice cleanup. But it was definitely needed for good performance before, so we shoudl be careful. Nori analyzer has the exact same thing (file has the same name) for ~10k hangul syllables.
