I'm aware of that the FSDirectory actually stores documents in a RAMDir until merge time. But the thing is that I also want to store the documents in the RAMDir as snapshots on the harddrive until they have been flushed down to the FSDir. So I won't loose any documents in a crash.
Does anybody have any proper solution for this? Maybe it's better to refactor the Lucene code so it fires an event when the merge occurs? / Marcus -----Ursprungligt meddelande----- Från: Erick Erickson [mailto:[EMAIL PROTECTED] Skickat: den 28 juni 2006 15:41 Till: java-user@lucene.apache.org Ämne: Re: Flushing RAMDir into FSDir Kind of a tangential response, but there was a discussion a while back about RAMdir .vs. FSDir that you probably want to search for and look over. As I remember (and I only glanced at it) the statement was made that the FSDir *is* a RAMdir, at least for a while. This implies that there es little to be gained by what you are doing. Here's a quote from Yonik "For indexing, even if you open IndexWriter with a FSDirectory, it internally uses RAMDirectory to buffer until it reaches maxBufferedDocs." See the thread IndexWriter.addIndexes & optimization Of course I don't fully understand your problem space, so your judgement has to control. But do you have any metrics indicating that what you are doing actually helps?
