You mean something like "store all keys with an even hash value on server X, and all keys with an odd hash value on server Y"? You can do this yourself in your application: Just hash the value and then send the request to the corresponding

It's unfortunate, but a lot of people participating in these discussions have no clue. They read that CouchDB claims to support "ACID" and then conclude that it fulfills the C in CAP. Now in reality, CouchDB isn't ACID compliant because it

Mysql Cluster performs 2phase commit for every transaction, so availability is not guaranteed.

FathomDB and SQL Azure are heading into that direction but both are still in their infancy, i.e. don't even support replication. But at least there's hope that these will offer a solution in the not-too-distant future.

If they want to offer Drizzle to customers, they probably need something like FathomDB. Considering that they're already collaborating, I could see them acquiring FathomDB sometime soon.

I don't think it would be hard. Just create a Windows application that hosts an IE ActiveX control and hides its main window. Or even better: When the user's screen saver is running, start a full-blown IE window and control it through Wind

How is it easy to disprove? The trojan could delete itself after downloading CP. Should be impossible to reconstruct what happened exactly.

I agree with your statement. I'm just unhappy that the article gives arguments in favor of Mongo that equally well apply to any SQL database. I would have liked more insights into the actual performance differences.

Most of the things the article talks about are actually possible in a SQL database. You can easily store JSON data in table rows if you want; foreign keys and joins are just further options that SQL offers you and MongoDB doesn't. I also do

I think you're missing the fact that Dynamo uses sloppy quorums (see section 4.6 in the paper), i.e. writes don't have to happen on the first N members of the preference list. For example, if W=3 and the first 3 nodes in the preference list

An interesting idea would be to make a submission cost 1 Karma point. So people would only submit a story if they think it's reasonable that someone might upvote it.
