      Description

      Lucene uses a non-trivial baseline bytes of heap for each indexed
      field, and I know it's abusive for an app to create 100K indexed
      fields but I still think we can and should make some effort to reduce
      heap usage per unique field?

      E.g. in block tree we store 3 BytesRefs per field, when 3 byte[]s
      would do...
