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. |
