One of those questions that's difficult to google. We were running into issues the other day with speed of our svn repository. The standard solution to this seems to be "more RAM! more CPU!" etc. Which got me to wondering, are there any source-control systems that use a document/nosql database (mongodb, couchdb etc) for database? It se...

I am creating a pager that returns documents from an Apache CouchDB map function from python-couchdb. This generator expression is working well, until it hits the max recursion depth.

Had gone through some NoSQL concepts and MongoDB & CouchDB articles. It seems they will give more scope to build scalable web applications. But need some clarity whether they will support the following features as SQL Server does? Whether it supports database mirroring? Is there any size limitation of NoSQL database? Is it better to ig...
I know this is another question on this topic but I am a complete beginner in the NoSQL world so I would love some advice.

I'm working on an application where the end user defines what columns a database table should have based off column names in an Excel spreadsheet that gets uploaded or just by manually defining them before uploading the spreadsheet.

They'll supply some text and images for the page and the url that the page needs to be on. We need a data store for this. The criteria for the data store are simple and defined below. I am not familiar with CouchDB or M...
Hi, I'm currently using CouchDb to store tens of millions of documents of variable fields, of variable types. Unfortunately, creating permanent views for these documents takes an inordinate amount of time and is becoming quite an inconvenience. Are there other key/value databases out there whereby I can test ad-hoc queries easily and h...
