Actually Riak can be used in a way in which it is content-aware of JSON and XML documents. http://wiki.basho.com/Riak-Search---Indexing-and-Querying-Ri...

Cassandra allows you to specify the consistency of writes and reads per operation, so for these operations, it would be required to trade consistency for availability. Conflict resolution is done using timestamps on each column. At first, t

No delivery business would post a blog with a picture of their new Ford Taurus delivery car as if it was something impressive. That's the difference.

Perhaps for the applications of yesterday (like Basecamp) this is the case, but the real innovation taking place is around collecting massive amounts of data and processing it in interesting ways. These systems are used every day to make qu

Indeed. It boils down to their need for a durable cache. It's simply too expensive to try to cache every comment tree in RAM, and Cassandra's data model and disk storage layout is a really good fit for the structure of their data.

This is because people came to the table with unrealistic expectations. They were used to dealing with mature software based on decades old proven ideas and coming into very experimental territory expecting to get a smooth experience. Cassa

It would be really cool to see an architecture update post from them regarding where they are now and where they want to go. Pretty please? :)

You must be confused. ElasticSearch stores it's documents on the local hard drive.

Glad to hear! The Atlantic Monthly is the only magazine I subscribe to. The content is absolutely worth it, and I feel like I'm supporting something truly needed in society today.

How are spinning disks just an issue with NoSQL? This feels like a thinly veiled ad piece for MongoDB.

This, so much. Caching should never be a "5 minute" thing and should only be considered once all other options are exhausted. Once teams start to go down this road, they should also begin working on a longer-term strategy for denormalizatio

For those wondering, the real power comes when you use the support for functional indices in combination with XML. You can create indexes on fragments of the XML and perform some very nice queries against large sets of XML documents. Hey, I

Actually, this is empirical evidence of the validity of this approach gained through observation of successful, real-world implementations. I'm not saying it's good purely because it's from Amazon or because any one person said it was good,

That's a 24-hour-news-network-pundit grade straw man he's created there. The replication strategy used by Cassandra is sourced from the Amazon Dynamo design (shared with Riak and Voldemort) and is intentional. It's not a bug; it's the way i

Timestamps were chosen over vector clocks intentionally. "...the primary use case for classic vector clocks of merging non-conflicting updates to different fields w/in a value is already handled by cassandra breaking a row into columns." Se

The ranges are assigned by a per-node token. With 4 nodes like the cluster shown in the slides, you'd space the tokens apart appropriately for 25% of the range on each node. When you add a node, you need to decide if you want to rebalance t

Yup. Slides are best used as an illustrative tool.

FYI -- the presentation says "temporal data" is a bad use case for Cassandra, but that's a misuse of the word temporal. "Ephemeral data" is a better way to say that.

Cool, thanks for taking the time to go a bit more in depth on this. This is a topic I'm particularly interested in, so I'm looking forward to the follow-up.

Yes, single Redis, but multiple instances of the application backed with a single datastore is hardly revolutionary. This is the classic reason why people go with a stateless app layer, so that it's simple to scale at least a single tier of

How is this scalable? It seems like this is a single-instance solution that in theory could scale, but this isn't even proven, nor is a clear path given. The author throws out a few vague ideas, and seems to vastly underestimate the complex

Have you any useful examples of non-trivial Hadoop MapReduce jobs that can process input data at hundreds of megabytes per second?

Right... this would be a lot more interesting if they picked existing open source implementations and ran them unmodified. It's not like people can drop their unmodified software into this and make it scream like what V8 did to plain JavaSc

Successfully taking risks should be rewarded in any meritocracy. Portraying employees who took a risk by working for the company before they were making money hand over fist as undeserving is wrong.
