"Incremental Stream Processing using Computational Conflict-free Replicated Data Types" [paper]
'Unlike existing alternatives, such as stream processing, that favor the execution of arbitrary application code, we want to capture much of the processing logic as a set of known operations over specialized Computational CRDTs, with particular semantics and invariants, such as min/max/average/median registers, accumulators, top-N sets, sorted sets/maps, and so on. Keeping state also allows the system to decrease the amount of propagated information. Preliminary results obtained in a single example show that Titan has an higher throughput when compared with state of the art stream processing systems.'

Roshiak
a Riak-based clone of Roshi, the CRDT server built on top of Redis. some day I'll write up the CRDT we use on top of Voldemort in $work.

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

CRDT toolbox
'The CRDT toolbox provides a collection of basic Conflict-free replicated data types as well as a common interface for defining your own CRDTs'. - in Eric Moritz' github. Also includes some more links to CRDT background reading.
