[jira] Created: (SOLR-1176) slowness when use elevate

slowness when use elevate
-------------------------

                 Key: SOLR-1176
                 URL: https://issues.apache.org/jira/browse/SOLR-1176
             Project: Solr
          Issue Type: Improvement
          Components: search
    Affects Versions: 1.3
            Reporter: realx.lu


When I use the elevation component ,system cost much  memory and slow.

the elevation component maintains a FieldCache entry for
"id", to translate docid to uniqueKey to do a HashMap lookup.

The HashMap lookup could be the cause of a little slowness, but the
main culprit is probably the memory used by the FieldCache entry.
