Subject [jira] [Updated] (LUCENE-4279) Regenerate Snowball code so its not so heavy
Date Wed, 01 Aug 2012 16:30:03 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated LUCENE-4279:
--------------------------------

    Attachment: LUCENE-4279.patch

patch: no need to regenerate the ones from the website that arent in the package as they already
work this way (Irish/Basque/Catalan/Armenian)

I also added a thread safety test (just checkRandomData against all the languages).

> Spinoff from LUCENE-3841 (and several threads on the list)
> Currently each SnowballStemmer is pretty heavy since each instance also contains a bunch
of Among objects (part of the stemming rules).
> This normally shouldnt be a problem, except it seems challenging
> for tomcat users to tune their threadpools (basically they are creating
> lots of tokenstreams, so lots of SnowballStemmers)
> Newer snowball just makes these static, and its easy enough to just
> regenerate so these aren't so heavy, it doesnt fix the real problem but it also doesn't
hurt.
