[jira] Updated: (LUCENE-1592) fix or deprecate TermsEnum.skipTo
[ https://issues.apache.org/jira/browse/LUCENE-1592?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael McCandless updated LUCENE-1592:
---------------------------------------
Fix Version/s: (was: 2.9)
Moving out.
> fix or deprecate TermsEnum.skipTo
> ---------------------------------
>
> Key: LUCENE-1592
> URL: https://issues.apache.org/jira/browse/LUCENE-1592
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Index
> Reporter: Michael McCandless
> Priority: Minor
>
> This method is a trap: it looks legitimate but it has hideously poor performance (simple linear scan implemented in the TermsEnum base class since none of the concrete impls override it with a more efficient implementation).
> The least we should do for 2.9 is deprecate the method with a strong warning about its performance.
> See here for background: http://www.lucidimagination.com/search/document/77dc4f8e893d3cf3/possible_terminfosreader_speedup
