Just be aware that this limits you in several ways in terms of your data model. For examle, if you ever need to remove a value and then re-write it, you have to up the timestamp on your inserts in order for it to be re-inserted. Same thing if you sometimes need to actually overwrite said value in some different context than the concurrent writer case you're trying to solve. -- / Peter Schuller
