Jason Rutherglen commented on LUCENE-1313: ------------------------------------------ {quote}we should make with NRT is to not close the doc store (stored fields, term vector) files when flushing for an NRT reader. {quote} Agreed, I think this feature is a must otherwise we're doing unnecessary in ram merging. {quote}we'd need to be able to somehow share an IndexInput & IndexOutput; or, perhaps we can open an IndexInput even though an IndexOutput{quote} I ran into problems with this before, I was trying to reuse Directory to write a transaction log. It seemed theoretically doable however it didn't work in practice. It could have been the seeking and replacing but I don't remember. FSIndexOutput uses a writeable RAF and FSIndexInput is read only why would there be an issue? > Realtime Search > --------------- > > Key: LUCENE-1313 > URL: https://issues.apache.org/jira/browse/LUCENE-1313 > Project: Lucene - Java > Issue Type: New Feature > Components: Index > Affects Versions: 2.4.1 > Reporter: Jason Rutherglen > Priority: Minor > Fix For: 2.9 > > Attachments: LUCENE-1313.jar, LUCENE-1313.patch, LUCENE-1313.patch, > LUCENE-1313.patch, LUCENE-1313.patch, lucene-1313.patch, lucene-1313.patch, > lucene-1313.patch, lucene-1313.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
