TinyCDB is a very fast and simple package for 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.
