I still wonder how we make efficient use of this. If you are ordering the logs based on the returned sequence Ids you have to effectively delay writing to the log since documents ie. their threads come back async and out of order. Even worse if some thread picks up a flush it might block for a reasonable amount of time. I am not saying its impossible but before we jump on it and get into the DWPT hassle we should at least sketch out how to make use of this feature (lemme tell you this is not trivial to implement and requires a fair bit of refactoring). If somebody has thought about this I'd be happy if you could share you ideas here! simon > > -Yonik > http://www.lucene-eurocon.com - The Lucene/Solr User Conference > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org > For additional commands, e-mail: dev-h...@lucene.apache.org > > --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
