Hi Ralf,
Seeing that 6.8 was renamed to 7.0 , was this change postponed to 7.1, or will it still be in 7.0 (as part of the general API breakage)? I find the notion of duplicate filenames quite confusing.
due to substantial changes in our APIs, and the long list of new features, we decided to upgrade our version number a major one. We'll keep our deadline, though!
In a future version (probably 7.1), we'll add another indirection to our document index that allows us faster checks for unique file names. While this isn't a major issue for smaller collections, we need this extension if millions of documents are stored in a single database (and we had some former use cases in which the filename was completely irrelevant and thus redundant). For now, the REPLACE command should do what you expect (but note that it may take some more time).
Thanks, Christian
