J. Bernstein's constant database package: a small file format and toolset for creating immutable key-value databases with fast lookups and atomic replacement. It is aimed at workloads where data is rebuilt wholesale and then read many times. ### Projektgeschichte The official cdb site describes cdb as a fast, reliable, simple package for creating and reading constant databases, with successful lookups in large databases normally taking two disk accesses and unsuccessful lookups one. The official format page republishes Bernstein's original 19960914 document, 'A structure for constant databases,' which defines the core cdb file layout, hash tables, records, little-endian 32-bit quantities, and hash function. The official download page records cdb-0.55 on 1996-09-22 as the first release, cdb-0.70 on 2000-02-17 as an almost complete API rewrite with mmap suggested by Ken Lalonde, cdb-0.75 on 2000-02-19 as a bug-fix and performance release, and a 2025-10-21 release adding cdb64 support, configure/make install support, and updated documentation. ### Adoptionsgeschichte cdb's adoption has been unusually long-lived for a tiny database format. The official site lists independent support packages and bindings in Perl, Ruby, Go, Rust, Python/Node wrappers through cdb64-rs, and TinyCDB wrappers. The Homebrew input also records cdb packages in Homebrew, MacPorts, and Nix. ### Wie es verwendet wird cdb is used when a program needs a compact, immutable lookup table that can be regenerated atomically. The package includes cdbmake for building databases, cdbget for lookup, cdbdump for dumping records, cdbstats for inspection, and a C read API documented on the official site. ### Warum Paket-Nerds sich dafür interessieren For package nerds, cdb is part of the D. J. Bernstein software lineage and a canonical example of a tiny, stable file format that escaped its original codebase. Its appeal is the combination of predictable lookup behavior, crash-safe replacement, public-domain-style licensing in packaged builds, and easy reimplementation in many languages. ### Zeitleiste - 1996-09-14: Original cdb format document date on the official format page. - 1996-09-22: cdb-0.55 first release on the official download page. - 2000-02-17: cdb-0.70 rewrote almost everything from scratch and incorporated mmap. - 2000-02-19: cdb-0.75 fixed a database creation bug and improved cdbmake performance. - 2025-10-21: Official release added cdb64 support and modern configure/install support. ### Related projects - The official intro page lists cdb64, cdb64-rs, CDB_File, cdb-full, CDB::TinyCDB, and Go implementations as packages that support the cdb or cdb64 formats. ### Quellen - - - - - - ## Sicherheitshinweise broad file, network, media, or database tool signal. - **Geiger-Risiko:** blue / mittel - broad file, network, media, or database tool signal ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cdb - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - Nix - cdb: normalized package name match | nixpkgs package indexes: pkgs/by-name/cd/cdb/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - MacPorts - cdb: normalized package name match | MacPorts ports tree: databases/cdb/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Verwandte Links - [Secret-risk packages](https://pkg.so/de/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/de/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Networking and protocol packages](https://pkg.so/de/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [lmdb](https://pkg.so/de/brew/lmdb/) - Shares pkgdb curated category or tags: cli, data, database, key-value-store. - [sdb](https://pkg.so/de/brew/sdb/) - Shares pkgdb curated category or tags: cli, data, database, key-value-store. - [kyoto-cabinet](https://pkg.so/de/brew/kyoto-cabinet/) - Shares pkgdb curated category or tags: cli, data, database, key-value-store. - [qdbm](https://pkg.so/de/brew/qdbm/) - Shares pkgdb curated category or tags: cli, data, database, key-value-store. - [kyoto-tycoon](https://pkg.so/de/brew/kyoto-tycoon/) - Shares pkgdb curated category or tags: cli, data, database, key-value-store. - [mysql](https://pkg.so/de/brew/mysql/) - Shares pkgdb curated category or tags: cli, data, database. - [postgresql@14](https://pkg.so/de/brew/postgresql-14/) - Shares pkgdb curated category or tags: cli, data, database. - [postgresql@16](https://pkg.so/de/brew/postgresql-16/) - Shares pkgdb curated category or tags: cli, data, database. - [tinycdb](https://pkg.so/de/brew/tinycdb/) - Local metadata places this package in an adjacent workflow.
