Subject [jira] Commented: (LUCENE-2960) Allow (or bring back) the ability to setRAMBufferSizeMB on an open IndexWriter
Date Tue, 15 Mar 2011 19:40:30 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007123#comment-13007123

Robert Muir commented on LUCENE-2960:
-------------------------------------

Its exactly the lack of consensus we see here, thats why I am 100% against having the setter
approach.

I'm totally against some deprecation/undeprecation loop because we in future releases another
setting
wants to be "live".

It seems the only way we can avoid this, is for javadoc to be the only specification as to
whether a setting
does or does not take effect "live".

> In 3.1 the ability to setRAMBufferSizeMB is deprecated, and removed in trunk. It would
be great to be able to control that on a live IndexWriter. Other possible two methods that
would be great to bring back are setTermIndexInterval and setReaderTermsIndexDivisor. Most
of the other setters can actually be set on the MergePolicy itself, so no need for setters
for those (I think).
