The "Why are all Views in a single Index" page has been changed by BenjaminYoung: http://wiki.apache.org/couchdb/Why%20are%20all%20Views%20in%20a%20single%20Index?action=diff&rev1=2&rev2=3 Comment: added jchris' tweet about back refs }}} Here view1 and view2 have exactly the same map function. If they were in different design documents, there would be two b-trees (in two different index files) for exactly the same data. Now, if they are in a single design document, we use one b-tree only, but we save disk space and update time by only updating one btree instead of two. Of course, this is easy only because we use one single index file for a design document with multiple views. + == Other Reasons: == + ||<tablewidth="100%"> {{https://si0.twimg.com/profile_images/1611440478/IMG_0049_normal.jpg|jchris}} ||'''jchris'''<<BR>>@bigbluehat @fdmanana also a combined index file can keep a single index of back refs from docids to rows, for invalidating old rows<<BR>> [[https://twitter.com/jchris/status/169514764693803010|2/14/12 3:14 PM]] || +
