Subject [jira] Updated: (LUCENE-1313) Realtime Search
Date Thu, 30 Apr 2009 21:59:30 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-1313?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Rutherglen updated LUCENE-1313:
-------------------------------------

    Attachment: LUCENE-1313.patch

* Ok, fixed the ensureContiguousMerge exception by asking the
mergePolicy (not ramMergePolicy) to evaluate the ram segment
infos as an optimize to directory. Now all the current tests
pass. 

* The patch is cleaned up a little, needs more, and further test
cases.

* IndexWriter doesn't accept setRAMDirectory anymore, it needs to
be passed into the IndexWriter constructor. This because we
can't run the system and the ram dir is changed in the middle of
an operation.

> Realtime search with transactional semantics.  
> Possible future directions:
>   * Optimistic concurrency
>   * Replication
> Encoding each transaction into a set of bytes by writing to a RAMDirectory enables replication.
 It is difficult to replicate using other methods because while the document may easily be
serialized, the analyzer cannot.
> I think this issue can hold realtime benchmarks which include indexing and searching
concurrently.
