Hi all, My client decided to change the name of the project and requires that I change the domain names in our SimpleDB. I could not find any way, service, API call or tool to allow me to do that.

These two queries are giving the same result, for example: select * from cbcallers where calls_completed is not null order by calls_...

I'm writing a python script to select, insert, update, and delete data in SimpleDB. I've been using the simpledb module written by sixapart so far, and it's working pretty well.

The benefits of a non-relational database (such as a key-value pair storage) are evident when used in large scale datasets (google, facebook, linkedin). How do you think small to medium sized applications can benefit from using non-relational databases? ...
Sorry if this question is somewhat subjective. I am new to 'could store', 'distributed store' or some concepts like this. I really wonder what do they have in common and want to get an overview on all of them. What do I need to prepare if I want to write a product similar to this? ...

I would like to increment the foo value for each item every 60 seconds, until it ...

Hi, I'm using C# and the AWSSDK library form Amazon to test a few things in SimpleDB. All going well so far. However, I am trying to come up with a neat way of retrieving all Attributes that are applicable to a Domain. This is proving to be tricky without having to retrieve an Item, and obviously I can get the list of attributes the...
I just read a little about resque here and how you use redis as a "advanced key-value store" for the jobs. As you might know you can use resque on multiple machines to process the jobs: Workers can be given multiple queues (a "queue list") and run on multiple machines. In fact they can be run anywhere with network access to the Redi...
