[jira] [Created] (LUCENE-5670) org.apache.lucene.util.fst.FST should skip over outputs it is not interested in

Christian Ziech created LUCENE-5670:
---------------------------------------

             Summary: org.apache.lucene.util.fst.FST should skip over outputs it is not interested in
                 Key: LUCENE-5670
                 URL: https://issues.apache.org/jira/browse/LUCENE-5670
             Project: Lucene - Core
          Issue Type: Improvement
    Affects Versions: 4.7
            Reporter: Christian Ziech
            Priority: Minor


Currently the FST uses the read(DataInput) method from the Outputs class to skip over outputs it actually is not interested in. For most use cases this just creates some additional objects that are immediately destroyed again.

When traversing an FST with non-trivial data however this can easily add up to several excess objects that nobody actually ever read.
