HAの構成

FD1

FD1
・検証はLAのためAshburnリージョンで実施 ※現在は東京・⼤阪でも利⽤可能
・３つのノードを持つグループレプリケーション構成
⇒インスタンス/ストレージのコストは3倍
・プライマリに障害が発⽣するとセカンダリが昇格
※3つのノードにping応答は有り、3306ポートは接続不可

HA障害検証

■検証⽅法
・コンソールからスイッチオーバーを⾏った時の応答を確認
・１秒間隔でSQL⽂(selectまたはupdate・insert)をmysqlコマンドで発⾏
■結果
・GUIのステータスが「更新中」⇒「アクティブ」に戻るまで約6分
・select⽂は、全て正常応答
・update・insert ⽂は、36秒間エラー応答
⇒更新処理のエラー内容：
ERROR 1290 (HY000) at line 1: The MySQL server is running with the --
super-read-only option so it cannot execute this statement

複数のデータソースの情報を仮想的に統合し、1画⾯上で複数のKPIを確認することが可能です
※Motion BoardのMDS対応(Certify)については、ウイングアーク社と協議中。
現時点では案件ベースで相談乗って頂けるとのこと。

■検証⽅法
・BIツールのMotionBoardで接続を⾏ってみる
・MotionBoardでMDS HAへ接続した状態でスイッチオーバーを⾏い、
操作を継続して⾏えるかを確認する
■結果
・通常稼働時にMotionBoardからMDS HAへ問題無く接続できた
・スイッチオーバー実施後もMotionBoardからエラー無く接続できた
BI接続検証

■MotionBoardの接続設定
・MDS HAへの接続設定はMySQLと同じ
BI接続検証
MDS HA特有の設定は無く、
・通常のMySQL
・スタンドアロンのMDS
と同様

BI接続検証
①MotionBoardで
MDS HAへ接続した状態
②スイッチオーバーを
実⾏
③MotionBoardでエラー無く
データを表⽰できることを確認

■測定⽅法
mysqlslapとsysbenchを使⽤して、
1万レコード作成、5ユーザーから合計30万回クエリを実⾏し、処理にかかった時間を記録する。
10回×1セットとしてテストして、セット間にテーブル削除再作成を⾏い3回の平均値を取得する。

・検索系の処理時間は「MDS/HA(リージョナル) > MDS/HA(AD固有)」となっている。
・更新系の処理時間は「MDS/HA(リージョナル) > MDS/HA(AD固有) > MDS HAなし」のようになっており、
MDS/HA(リージョナル) は「MDS HAなし」の2倍程度の処理時間がかかっている。
性能に差が出ている理由として、MDS/HAはグループレプリケーションにて他のノードと同期を⾏っていることが原因と推測できる。
MDS/HA(リージョナル) は他のノードとAD間で同期を⾏うため、FD間で同期を⾏うMDS/HA(AD固有)よりネットワークのレイテンシ
が⾼く、時間がかかっているものと思われる。

⇒ただし、レプリケーションにて問題が発⽣し、その後再開しようとしても
現状ではMDS側は再構築が必要になりそうです…次ページ

■MDS再構築が必要となるパターン
・前提としてMDSはGTIDベースのレプリケーションのみをサポート
・レプリケーションにて問題が発⽣した際、レプリケーション元と先のデータを修復
する必要がある
・レプリケーション先であるMDS側でGTIDを再設定する⇒ここでエラーが発⽣
エラーの原因は、gtid_purgedパラメータに再度GTIDを設定するにあたり、
RELOAD権限の不⾜により、”reset master”コマンドが実⾏できない

■再構築になった例
①デフォルトのキャラクタセットは
AWS Aurora⇒ltain1 MDS⇒utf8mb4と差異がある事に気付かずに
レプリケーションを⾏おうとし、カラムの型の差異でエラーになった
②AWS Auroraのデフォルトキャラクタセットをutf8mb4に変更
③MDS側にてgtid_purgedの再設定にあたり、
”reset master”が実⾏できず、MDSを再構築することになる。
■対応
“reset master”の代替機能がMDSに追加されるようオラクルサポートから、
機能追加リクエスト(FR)を⾏っており、今後の改善に期待です！

総括

■良い点
・グループレプリケーションによるHA構成が容易に構築できる
■悪い点
・更新処理の性能に懸念がある
（現状ではスタンドアロン構成の2分の1程度）
■今後に期待する機能
・無停⽌アップグレード (HAの真⾻頂だと思います！)
・セカンダリメンバーへのアクセス(参照処理性能の向上のため)
