m3-db/smalldb

This package will maintain a copy of a data structure on secondary storage, and will update the secondary storage as updates are made to the data structure. A client can use this package to ensure that the current value of the data structure can be recovered after any crash. This package is efficient: the cost of recording an update is about one disk write.
