Count me amongst the dissenters. Optimize can make a lot of sense, and that's why it still exists. People should be careful to not assume they need to optimize to get good performance, but people assuming that no one should optimize are making just as big of a mistake IMO. > When/if a configuration option becomes available so I can do a commit that > expunges deletes even when there are only a few deleted documents, or if I > can figure out how to add that option myself, I will be able to eliminate > full optimization entirely. Expunging a single delete from a segment involves re-writing the entire segment, so it's just as bad as optimize (assuming most segments have a deletion). You might as well get the benefit of the optimize as well. -Yonik http://lucidworks.com
