[hackers-jp: 38] [HACKERS] Proposal for a cascaded master-slave replication system

[TANIDA Yutaka]

谷田です。

Core memberの一人、Jan Weickがレプリケーションの提案をしています。

# またレプリケーション？いったいいくつあるのやら。

私はレプリケーションに関する知識が皆無なのであれですが、興味深いのは比較
的複雑な構造を可能にしているそのコンセプトですね。うまくノードつなぐこと
で、複数のデータベースがお互いにデータを補完しあうようにできるようです。

とりあえず元メール全文引用しておきますので、私よりレプリケーションに詳し
い誰かに解説をお願いしたいところです:-)
