cdb is a fast, reliable, lightweight package for creating and reading
constant databases. Its database structure provides several features:
* Fast lookups: A successful lookup in a large database normally takes
just two disk accesses. An unsuccessful lookup takes only one.
* Low overhead: A database uses 2048 bytes, plus 24 bytes per record,
plus the space for keys and data.
* No random limits: cdb can handle any database up to 4 gigabytes. There
are no other restrictions; records don't even have to fit into memory.
Databases are stored in a machine-independent format.
* Fast atomic database replacement: cdbmake can rewrite an entire
database two orders of magnitude faster than other hashing packages.
* Fast database dumps: cdbdump prints the contents of a database in
cdbmake-compatible format.
cdb is designed to be used in mission-critical applications like e-mail.
Database replacement is safe against system crashes. Readers don't have
to pause during a rewrite.
