Redis weekly update #1—Hashes and... many more! Hashes were the big missing data type in Redis—support is only partial at the moment (no ability to list all keys in a hash or delete a specific key) but at the rate Redis is developed I expect that to be fixed within a week or two. 13th March 2010, 12:06 am
A Collection Of Redis Use Cases. Lots of interesting case studies here, collated by Mathias Meyer. Redis clearly shines for anything involving statistics or high volumes of small writes. 16th February 2010, 3:04 pm
FleetDB (via) Yet Another Key-Value Store: Schema-free, JSON protocol, everything cached in RAM, append-only log for durability, multi-record transactions... but what’s really interesting about this one is that it’s written in Clojure and takes full advantage of that language’s concurrency primitives. The prefix operators used by the select API hint at its Lisp heritage.

New Redis ZINCRBY command (via) Just added to Redis, a command which increments the “score” for an item in a sorted set and reorders the set to reflect the new scores. Looks ideally suited to real time stats, and I’m sure there are plenty of other exciting uses for it. 22nd December 2009, 8:38 pm
Crowdsourced document analysis and MP expenses
As you may have heard, the UK government released a fresh batch of MP expenses documents a week ago on Thursday. I spent that week working with a small team at Guardian HQ to prepare for the release. Here’s what we built: [... 2051 words]

Node.js is genuinely exciting
I gave a talk on Friday at Full Frontal, a new one day JavaScript conference in my home town of Brighton. I ended up throwing away my intended topic (JSONP, APIs and cross-domain security) three days before the event in favour of a technology which first crossed my radar less than two weeks ago.

When I worked at Amazon.com we had a deeply-ingrained hatred for all of the SQL databases in our systems. Now, we knew perfectly well how to scale them through partitioning and other means. But making them highly available was another matter. Replication and failover give you basic reliability, but it’s very limited and inflexible compared to a real distributed datastore with master-master replication, partition tolerance, consensus and/or eventual consistency, or other availability-oriented features.

Looking to the future with Cassandra. Digg are now using Cassandra for their “green badge” (one of your friends have dugg this story) feature—the resulting denormalised dataset weighs in at 3 TB and 76 billion columns. 9th September 2009, 9:26 pm
