#isucon チーム「ウー馬場ーイー222」でISUCON13本選に参加し30位になりました

 Posted on November 25, 2023  |  BABA Toshiaki

今年は予選なしで全員が一発本選なので、昨年に引き続き本選に参加です。

というわけで、今年も例年通り @matsuu、 @ishikawa84g と参加しました。

チーム名が「シン・ウー馬場ーイー2」から「ウー馬場ーイー222」になり新たなスタートを切りました。 222はチーム番号です。縁起が良いですね。

今年もとても楽しめました。運営のみなさんありがとうございました。

結果はまだわからないけど、最終スコアは 49,344 といまひとつ。

ワンチャン30位以内にならないかなーと希望的観測。 →（繰り上げがあり）30位でした！ギリで上位粗品圏内！

役割分担はこれまたいつも通りこんな感じです。

  • @ishikawa84g サイトやレギュレーションやコードやログやDiscordを見る情報官
  • @matsuu バリバリ実装する前衛
  • @netmarkjp 司令塔

ちなみに写真はソラマチにある蟻月のモツ鍋（ランチ）です。

今年はハナからGoで

毎年「今年こそRust」というもののなかなか踏み切れず。特に状況が改善したりしなかったので、今年はRustはハナから諦めてGoでやりました。

実装レベルの詳しいことは@matsuuが書いてくれると思うので、自分は別の観点で。

去年はDBを分割する決断ができず本選の結果が奮わなかったので、今年はDBを分割するか判断できるようツールを用意してみました。

コードの中からSQLを抽出して、どこでそれを呼び出しているか一覧にするツールです。 クエリー自体のhash値を併記しているので、DBのスローログで発見されたクエリーがどこにあるか発見しやすくなります。

関数呼び出しを追跡しているので、SQLを呼び出している関数の呼び出し元を辿ることができます（-notrace をつければ定義箇所だけ）。

デフォルトはtextフォーマットだけど、tsvやjsonにもできます。 標準出力に出すから | vim -R - -c "set ft=sql" とかでSQLを見るのも楽です。

スロークエリーログで問題のクエリーを発見→ツールで呼び出し元を発見→どう対応するか決める という流れで活用できます。

だがしかし

...これを作って意気揚々と本番に臨んだものの、入力に1ファイルしか想定しておらず、今回は使えませんでした。

悔しかったので本選終了後にいじったところ、30分くらいで複数ファイルに対応できました。 AST触るのは始めてだったけど、優秀なChatGPTのおかげでなんとか動いているようです。

というわけで、来年はがんばろう。。。

なお終了後に改修した最新版だとこんな感じで使えます。 これは初期コードに適用してみたところ。

SELECT * FROM livestreams WHERE id = ? （Checksum B83ADB51427F2D680B7655A83409ABA0）が複数箇所で定義されているのがわかります。 あと fillLivecommentResponse や fillLivecommentResponse がいろいろ呼び出されていることがわかります。
