CouchApp really is excellent marketing, folks, and I congratulate you. As I'm sure you know, any database with an HTTP interface will do exactly the same thing. Riak, for example. I leave you to your normal round of thoughtful, reasoned

I think I see your confusion. The headline is not the message thread. It's a link you need to click. Then you can read the actual message thread. Hope this helps!

That certain services can't yet be moved to AWS is not an an indicator AWS is compromised. Several services, for example the payments infrastructure, are subject to regulations that make it challenging to implement _at all_, much less in a

"...told me that engineers at Amazon were generally forbidden from using AWS due to security concerns." The opposite is the case: there has been a huge push for some time to move (significant) parts of Amazon retail to AWS. It's extremely

It seems unlikely most users on the Internet could even parse your suggestion, much less execute it. That doesn't make them stupid, just not experts in the subject. Instead they rely on experts, like you, to make the right choices for the

I'm very excited to see where this sort of pattern goes. Swiss-army knife middleware projects are much less interesting to me than the more minimalist approach possible directly using 0MQ.

From the VoltDB FAQ ( http://community.voltdb.com/faq#id545596 ): Key-Value stores are a mechanism for storing arbitrary data (i.e. values) based on individual keys. Distributing Key-Value stores is simple, since there is only one key. Howe

From your earlier comment: "Due to it’s unique single-threaded architecture..." That would be a single thread per partition, right? Are those partitions automatic or might a developer have to consider their creation carefully based on how

It is a triumph of vendor marketing (Hi, John Hugg!) that reasonably informed engineers think ACID == SQL/relational and that NoSQL == EC. Both are false. As a couple of examples, have a look at Google Percolator http://research.google.com

Irrelevant contrarian opinion that adds nothing to the debate, but indicates with certainty I am more interested in being pedantic and scoring points than having a useful discussion.

Yes, you can go buy name-brand hardware (Dell, IBM, Sun, HP) in a special configuration not used anywhere else in your infrastructure and install an OS on it which you don't run on any other system, all just so you can have the honor of pay

Absent a metric for "scale" it isn't false, it's meaningless. Here is some context to help you distinguish how things work for online services as opposed to financials: As you are not printing money, you care about cost efficiency. This m

Vendors highly optimize for your case, and you find that their solutions work for you. Not a surprise. Different constraints and different requirements produce different solutions. Nobody is saying you are doing financial services storag

So you are aware, yours is the traditional response. Somehow, doing what Google and Facebook do is "easy" because not everything requires transactions. This is false both because scale like that makes almost everything difficult, and beca

In the specific case of FlockDB, that's actually not the case as the shards are modular. SQLShard is one implementation. There was an experimental Redis shard implementation, as well. You might be both overestimating the cost of building

If the answer is "Spend millions on Oracle", people will be motivated to ask a different question.

Schema rigidity is a canard originating with the same folks who think a hash is a type system. I encourage you to dismiss the folks who say things like that, rather than dismissing some very useful technologies.

Google and Facebook have all the money and talent required to deploy epic Oracle systems. Instead they use GFS and BigTable and Cassandra and HBase and Scribe and Hadoop and MySQL and a host of other systems. Amazon has massive Oracle dep

That was but one example out of many. Oracle is a great database. It isn't great at everything, however. Geographically distributed, fault tolerant, scale out architectures as often required for big online services? Not a great fit. Mu

The existence of great tools for relational databases is a compelling argument for using them. As I said in the article, starting off using a single, monolithic relational store is a successful approach employed by many, successful compani

As MongoDB did not exist at the time, it seems unlikely. Such things happen more than we might like, of course! "Also, the scenario you describe is as easily mitigated with hot failovers and offsite backups." This is a sadly wrong, though

Good question! The answer is that the "If..." evaluates to false: ops (and by that I hope you mean something more than facilities staff) has a far simpler set of problems with which to deal when the software is designed, implemented, and t

I purposefully ignored the tornado and so it did not hit my datacenter, tear off a section of the roof, kill all power sources, and drench my servers. Hard problems: solved.
