No. The copy is to keep an index available for searches while the optimise is happening. Also, to allow for rollback should something go wrong with the optimise. The simplest thing is to keep your commits low (I suspect you could ingest 35m documents with just one commit at the end). In that case, optimisation is not required (optimisation is to reduce the number of segments in your index, and segments are created by commits. If you don't do many commits, you won't need to optimise - at least you won't at the point of initial ingestion. Upayavira
