Description

ManifoldCF's reliance on a relational database limits its throughput and scalability. I am now convinced it is possible to build all the structures we need within a distributed key-value store like Voldemort, which has the nice side effect of permitting massive scaling. I envision there will be several layers to this project, some of which may have broader utility in the open-source community at large:

(1) An atomic serialization layer, which adds serialization capabilities to an non-transactional substrate;
(2) A transaction layer, which uses atomic serialization to build a notion of light transactions;
(3) A table and index layer, which defines SQL-like concepts of tables and btree indexes on top of the transaction layer, via a Java API;
(4) A generic "database abstraction" layer, which is capable of representing both standard SQL databases as well as this NoSQL variant, so that ManifoldCF can support both models.

This is obviously a major development task, and as such is not envisioned to be completed by the next standard release. Work will indeed need to be done in a branch.
