tectonica-kvs

Simple, yet powerful, framework (and approach) for handling a key-value store. It allows for multiple concurrent readers but a single concurrent writer to access each entry. It also provides a read-before-update mechanism which makes life simpler and keeps data consistent. Indexing and caching are also supported as part of the framework. The interface is intuitive and straightforward. This framework provides a base class, and a set of subclasses implementing it on several backend persistence engines, including in-memory (which is great for development).

The usage of this framework would probably yield the most benefit when used to prototype a data model, where changes are frequent and not backwards-compatible. However, in more than a few scenarios, this framework can be used in production. The heavy-lifting is done by the backend database and cache either way.
