プロジェクトの歴史

The official specification traces Kyoto Cabinet through the older Unix DBM line: original DBM, NDBM, SDBM, GDBM, TDB, Berkeley DB, QDBM, and Tokyo Cabinet. Hirabayashi wrote QDBM in 2003 to replace GDBM for performance reasons, Tokyo Cabinet in 2007 as a successor to QDBM, and Kyoto Cabinet in 2009 as another successor focused on space efficiency, parallelism, portability, usability, and robustness.

Kyoto Cabinet differs from Tokyo Cabinet by being written in C++ with an object-oriented API, a common interface across multiple database implementations, and portability goals that include non-POSIX systems. Its official page dates the work to the 2009-2012 FAL Labs period and points users toward Tkrzw as its successor.

採用の歴史

Kyoto Cabinet became a known package in Unix package managers because it offered an embeddable key-value store with language bindings and command-line utilities. It appealed to users who wanted DBM-style storage without running a full database server.

使われ方

The package installs libraries plus utilities such as kchashmgr, kctreemgr, kcpolymgr, and test tools. Typical uses are local key-value indexes, caches, compact persistent maps, data conversion jobs, and applications that need hash or ordered B+ tree storage behind a simple API.

パッケージ好きにとっての重要性

Kyoto Cabinet is package-nerd catnip because it is a whole database lineage compressed into a small C++ library and a pile of precise command-line tools. It is also a reminder of the DBM tradition that predates the Redis/LevelDB/RocksDB era but still solves many local storage problems with less moving machinery.

タイムライン
