Documentation

Overview

strdy (pronounced "sturdy") is a database for holding a string-to-string map. Keys and Values should not contain ASCII control characters, and particularly not tabs nor newlines.

It is not designed for large amounts of data that would not fit nicely in memory.

The in-memory data structure is a skiplist in lexical order of the keys.

The database is backed by a flat textfile, which is appended as records are inserted or updated.
