    nonblonde

    A Key/data Store

    Nonblonde is a key/value database. Nonblonde tables are backed by b-trees that organize their nodes as critical bit trees. It allows multiple tables per store, atomic updates, keys of unlimited size. Head and tail key compression and a variable block size reduce the database disk size. Disk blocks are never modified in place, for which the written database is always in an intended state and does not need repair or recovery.
