Subject [jira] [Created] (SOLR-12366) Avoid SlowAtomicReader.getLiveDocs -- it's slow
Date Wed, 16 May 2018 21:31:00 GMT
David Smiley created SOLR-12366:

             Summary: Avoid SlowAtomicReader.getLiveDocs -- it's slow
                 Key: SOLR-12366
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: search
            Reporter: David Smiley
            Assignee: David Smiley

SlowAtomicReader is of course slow, and it's getLiveDocs (based on MultiBits) is slow as it
uses a binary search for each lookup.  There are various places in Solr that use SolrIndexSearcher.getSlowAtomicReader
and then get the liveDocs.  Most of these places ought to work with SolrIndexSearcher's getLiveDocs
