If you update each document individually you need more disk space than if you use bulk updates on multiple documents at once (until compaction runs). You also need to take account for the views and their compaction. I have seen a view of 6,6GB before and 187MB size after compaction. I think, not sure on that though, it should also depend on how good your data compresses (if you use snappy). So I would say you have to try it out to get a rough idea how to dimension your file-systems. regards, Stefan
