Mnesia のレプリケーションを試す - cooldaemonの備忘録
Mnesia のレプリケーションをいろいろ試してみたのでメモ。 まずは、下記を mnesia_test.erl というファイル名で保存して、コンパイルする。 -module(mnesia_test). -include_lib("stdlib/include/qlc.hrl"). -record(store, {key, value}). -export([start/0, start/1, restart/1, set/2, get/1]). start() -> mnesia:start(), mnesia:create_schema([node()]), mnesia:create_table(store, [{attributes, record_info(fields, store)}]). start(Nodes) -> mnesia:start(), mnesia:chang
分散DBMS「Mnesia」の並列処理
はじめに Mnesiaは、Erlangという言語をベースとした並列プログラミング用のオープンソース開発環境であるErlang OTPに付属している高機能のデータベース管理システム（DBMS）です。Mnesiaは真の分散DBMSなので、世界中の何千ものノード間でデータを分散し、複製し、断片化することも朝飯前です。ユーザーがしなければならないのは、Mnesiaデータベースの分散先となるさまざまなErlangノードを実行することだけです。 Mnesiaという名前になった経緯は、少々眉唾ではありますが、もともとは「Amnesia（健忘症）」という名前だったものを、エリクソンの重役が「データベースに『物忘れ』を連想させる名前を付けるのはいかがなものか」と発言したことから、エンジニアが「A」の文字を取って「Mnesia」とし、「すべてを記憶するもの」の意味を持たせたと言われています。Mnesiaは、E
