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.
