@oranie さんのブログ記事への返信です。 たいへん遅くなりました。申し訳ないです。

repairとcompactionのコストが高すぎる

Cassandraにノードを追加する(Bootstrap)と、そのノードが担当するレプリカのデータを他のノードから取得します。 Repairはノードが保持するレプリカの整合性を検証して修復します。

どちらもデータを他のノードから取得しますが、ファイルを1つづつやり取りするため時間がかかるのは事実です。 この部分にまだまだ改善の余地があります。次のメジャーバージョンで抜本的に見直します。

Function::define = (prop, desc) ->
    Object.defineProperty this.prototype, prop, desc

class GetterSetterTest
    constructor: (@_obj = {}) ->

    # 'obj' is defined via the prototype, the definition proxied through
    # to 'Object.defineProperty' via a function called 'define' providing
    # some nice syntactic sugar.  Remember, the value of '@' is
    # GetterSetterTest itself when used in the body of it's class definition.

# Drop this file in config/initializers to run your Rails project on Ruby 1.9.
# This is three separate monkey patches -- see comments in code below for the source of each. 
# None of them are original to me, I just put them in one file for easily dropping into my Rails projects.
# Also see original sources for pros and cons of each patch. Most notably, the MySQL patch just assumes
# that everything in your database is stored as UTF-8. This was true for me, and there's a good chance it's
# true for you too, in which case this is a quick, practical solution to get you up and running on Ruby  1.9.
