Aerospike is the former Citrusleaf: http://www.dbms2.com/2012/08/27/aerospike-the-former-citrusleaf/
Citrusleaf acquired AlchemyDB and we are now incrementally porting AlchemyDB functionality to run on top of Citrusleaf’s proven distributed high-availability linearly-scalable key-value store. First functionalities planned are: Lua with DocumentStore functionality, Secondary Indexes, and Real-time map-reduce. Further down the road Pregel like Distributed GraphDB like functionality or some next generation StreamingDB may be integrated in. Incrementally building AlchemyDB on top of Citrusleaf will create a distributed computing fabric, functions can be shipped to data (that lies on a horizontally scalable low latency storage layer), and the functions can propagate their results across the fabric, calling other functions on them.
