There's "acid-state", which provides a log-based persistence model. I.e., it persists the modifications you make to the data structure.

Hello everyone,  I'm not sure if something like this already exists so I figured I would ask here first before I reinvent the wheel. What I need is a data structure that behaves like Data.Map, but is serialized to disk incrementally so I only have the overhead of writing what has changed every time.
