Let's say document A and B are ingested in parallell to = XMLUpdateRequestHandler in two separate threads. How far down the chain are the processing of these done in the two = separate threads? Is the full UpdateRequestChain run in the same thread as the incoming = request? Is analysis done in the request thread or in a single indexing thread? Are ADDs added to the same "commit queue", and then from COMMIT and down = to Lucene segment building everything is single-threaded? -- Jan H=F8ydahl, search solution architect Cominvent AS - www.cominvent.com= --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@lucene.apache.org For additional commands, e-mail: dev-help@lucene.apache.org
