Will the last person at Basho please turn out the lights? • The Register
Basho, once a rising star of the NoSQL database world, has faded away to almost nothing [...] According to sources, the company, which developed the Riak distributed database, has been shedding engineers for months, and is now operating as a shadow of its former self, as at least one buy-out has fallen through.

If Eventual Consistency Seems Hard, Wait Till You Try MVCC
ex-Percona MySQL wizard Baron Schwartz, noting that MVCC as implemented in common SQL databases is not all that simple or reliable compared to big bad NoSQL Eventual Consistency:
Since I am not ready to assert that there’s a distributed system I know to be better and simpler than eventually consistent datastores, and since I certainly know that InnoDB’s MVCC implementation is full of complexities, for right now I am probably in the same position most of my readers are: the two viable choices seem to be single-node MVCC and multi-node eventual consistency. And I don’t think MVCC is the simpler paradigm of the two.

Call me maybe: Carly Rae Jepsen and the perils of network partitions
Kyle "aphyr" Kingsbury expands on his slides demonstrating the real-world failure scenarios that arise during some kinds of partitions (specifically, the TCP-hang, no clear routing failure, network partition scenario). Great set of blog posts clarifying CAP

Riakking Complex Data Types
interesting details about Riak's support for secondary indexes. Not quite SQL, but still more powerful than plain old K/V storage (via dehora)

Cassandra, Hive, and Hadoop: How We Picked Our Analytics Stack
reasonably good whole-stack performance testing and analysis; HBase, Riak, MongoDB, and Cassandra compared. Riak did pretty badly :(

Basho | Alert Logic Relies on Riak to Support Rapid Growth
'The new [Riak-based] analytics infrastructure performs statistical and correlation processing on all data [...] approximately 5 TB/day. All of this data is processed in real-time as it streams in. [...] Alert Logic’s analytics infrastructure, powered by Riak, achieves performance results of up to 35k operations/second across each node in the cluster – performance that eclipses the existing MySQL deployment by a large margin on single node performance. In real business terms, the initial deployment of the combination of Riak and the analytic infrastructure has allowed Alert Logic to process in real-time 7,500 reports, which previously took 12 hours of dedicated processing every night.'

Twitter discussion here: https://twitter.com/fisherpk/status/294984960849367040 , which notes 'heavily cached SAN storage, 12 core blades and 90% get to put ops', and '3 riak nodes, 12-cores, 30k get heavy riak ops/sec. 8 nodes driving ops to that cluster'. Apparently the use of SAN storage on all nodes is historic, but certainly seems to have produced good iops numbers as an (expensive) side-effect...
