creating and reading constant data bases, a data structure introduced by Dan J. Bernstein in his cdb package. It may be used to speed up searches in a sequence of (key,value) pairs with very big number of records. Example usage is indexing a big list of users - where a search will require linear reading of a large /etc/passwd file, and for many other tasks. It's usage/API is similar to ones found in BerkeleyDB, gdbm and traditional *nix dbm/ndbm libraries, and is compatible in great extent to cdb-0.75 package by Dan Bernstein. CDB is a constant database, that is, it cannot be updated at a runtime, only rebuilt. Rebuilding is atomic operation and is very fast - much faster than of many other similar packages. Once created, CDB may be queried, and a query takes very little time to complete.
