LogDB is a Go library for efficient log-structured databases. A log-structured database is a very simple data store where writes are only ever appended to the database, there are no random-access writes at all. To prevent the database from growing indefinitely, a contiguous chunk of entries can be removed from either the beginning or the end.

This library is efficient and provides ACID consistency guarantees: an entry is either stored or it is not, even in the event of power loss during execution the database cannot be left in an inconsistent state.

The godoc is available online.

Very early days. The API is unstable, and everything is in flux.
