Subject [jira] [Commented] (LUCENE-3736) ParallelReader is now atomic, rename to ParallelAtomicReader and also add a ParallelCompositeReader (that requires LogDocMergePolicy to have identical subreader structure)
Date Tue, 07 Feb 2012 15:26:59 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3736?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13202463#comment-13202463
] 

Uwe Schindler commented on LUCENE-3736:
---------------------------------------

Please keep the chained APIs, otherwise please also change all toString() methods in whole
Lucene to no longer chain and rename all classes to no longer be called Builder with build()
as method. If you keep the class names and disallow chaing you break the pattern and that
will confuse people more.

For me the issue is closed as I disagree, somebody else can do this :(

> The plan is:
> - Move all subreaders to ctor (builder-like API. First build reader-set, then call build)
> - Rename ParallelReader to ParallelAtomicReader
> - Add a ParallelCompositeReader with same builder API, but taking any CompositeReader-set
and checks them that they are aligned (docStarts identical). The subreaders are ParallelAtomicReaders.
