David Smiley created LUCENE-9455:
------------------------------------
Summary: ExitableTermsEnum (in ExitableDirectoryReader) should
sample next()
Key: LUCENE-9455
URL: https://issues.apache.org/jira/browse/LUCENE-9455
Project: Lucene - Core
Issue Type: Improvement
Components: core/other
Reporter: David Smiley
ExitableTermsEnum calls "checkAndThrow" on *every* call to next(). This is too
expensive; it should sample. I observed ElasticSearch uses the same approach;
I think Lucene would benefit from this:
