Subject [jira] Created: (LUCENE-2575) Concurrent byte and int block implementations
Date Thu, 29 Jul 2010 05:05:19 GMT
Concurrent byte and int block implementations
---------------------------------------------

                 Key: LUCENE-2575
                 URL: https://issues.apache.org/jira/browse/LUCENE-2575
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
    Affects Versions: Realtime Branch
            Reporter: Jason Rutherglen
             Fix For: Realtime Branch


The current *BlockPool implementations aren't quite concurrent.
We really need something that has a locking flush method, where
flush is called at the end of adding a document. Once flushed,
the newly written data would be available to all other reading
threads (ie, postings etc). I'm not sure I understand the slices
concept, it seems like it'd be easier to implement a seekable
random access file like API. One'd seek to a given position,
then read or write from there. The underlying management of byte
arrays could then be hidden?
