・SQLパーサー＆オプティマイザ部分の理解
ビルド参考：
開発ソースツリーを使用して MySQL をインストールする
環境はAWS EC2 t1.microインスタンス
１、ソースの取得
[centos@mirage mysql-server]$ git clone https://github.com/mysql/mysql-server.git [centos@mirage mysql-server]$ git branch -r origin/5.5 origin/5.6 origin/5.7 origin/HEAD -> origin/5.7 origin/cluster-7.2 origin/cluster-7.3 origin/cluster-7.4 [centos@mirage mysql-server]$ git branch 5.6 * 5.7
２、ビルド環境の準備
動きを追うためデバッグオプションつきでビルド。

5.7ではboostが必要らしい
最新版にはこだわらないので5.6に切り替えてリトライ
[centos@mirage bld_debug]$ pwd
/home/centos/mysql-server/bld_debug
[centos@mirage bld_debug]$ cd ..
[centos@mirage mysql-server]$ git checkout 5.6
Switched to branch '5.6'
[centos@mirage mysql-server]$
