Subject [jira] Commented: (LUCENE-2548) Remove all interning of field names from flex API
Date Sun, 18 Jul 2010 11:39:50 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12889609#action_12889609

Shai Erera commented on LUCENE-2548:
------------------------------------

Why remove Term? I think it's a nice API, and for most cases, a term will still be a Term
and not a BytesRef + Field. Isn't it a convenient class? Is there an alternative one?

> In previous versions of Lucene, interning of fields was important to minimize string
comparison cost when iterating TermEnums, to detect changes in field name. As we separated
field names from terms in flex, no query compares field names anymore, so the whole performance
problematic interning can be removed. I will start with doing this, but we need to carefully
review some places e.g. in preflex codec.
> Maybe before this issue we should remove the Term class completely. :-) Robert?
