We are using CouchDB for production and happy with it. It is much more lightweight rather then MongoDB yet powerful. (For our needs at least). But sometimes you have situations that some code deleted/spoiled your Couch Database data. We had some bugs leading to deleting indexes. However compaction have not been run and here is the decision. There are several ways for different situations. I'll try to cover them all. So for deleted CouchDB documents you need to: 1. Make sure your document with this id is Deleted. To do it you need to request CouchDB for this document. E.g. with this string: $db/$id Where  $db  is your CouchDB database name and  $id  is your deleted document id it should return something like this: { "error" : "not_found" , "reason" : "deleted" } 2. Get all the revisions of the deleted document. With this request: $db/$id?revs= true &open_revs=all Where $db is your CouchDB database name and $id is ...

Our project will have a new architecture changes in future. We've chosen from different tech. But now we 're experimenting with CouchDB a bit. It may become a part of our new architectural Changes. I'll try to cover most of newbies observations with CouchDB for Python(Django) programmer, planning to use it in your project. First article will be, unsurprisingly, installing CouchDB under Mac OS X. It, sure, has some inches that you need to scratch. So let's roll... CouchDB is not a simple SQL database like you used to install before. It has own server to accept connections. And, in fact, you can work with database from your browser GUI (without other server proxy, like Django or ...). Anyway it will not be our target. Building JS UI is quite easier with CouchDB and changes your logic dramatically. To build UI with Python we need some proxy parts. Anyway, again, CouchDB is a standalone server, that runs on your server's port and talks to your APP/Browser/wha...
