We've been using Clustrix in production for two years at TheLadders. Very satisfied with performance, wide feature set, low maintenance cost. Saved money on: not doing sharding; eliminating a full-time DBA position; repurposing hardware used for MySQL slave farm and storage. Clustrix support is excellent.
