わかりました、件名に対する明白な答えは次のとおりです。70GBです。しばらくお待ちください。しかし、私を聞いてください。
以前mysqlimportは、データファイル（mysql標準タブ区切り形式）をすばやくロードしていました。mysqlimportコマンドが完了するまでに約4時間かかりました。この間、ディスクは容量（〜50MB /秒のディスクアクティビティ）で実行されていました。
しかし、完了してからさらに5時間経ちましたが、次のような単純なクエリを実行することはできません。
select * from my_big_table limit 1
そのクエリを実行すると、（一見）無期限にブロックされます。クエリが実行されていない場合、ディスクアクティビティ（1つのmysqlプロセスが3MB /秒の読み取りと書き込みを実行し、別のmysqlプロセスが数MB /秒の読み取りアクティビティを実行している）が表示されます。これは、実行してから一定mysqlimportです。また、1つのmysqlスレッドがほぼ100％実行されているように見えることもわかりmysqlimportます。
私の推測では、mysqlはバックグラウンド（1億5000万レコード、InnoDB）でインデックス作成などを処理しており、それがテーブルをクエリする私の能力を妨げているものです。しかし、それを確認する方法や、どのような活動が行われているのかを確認する方法がわかりません。または、いつ終了するかを見積もります。
余分な詳細：
なぜ70GBのテーブルがmysqlに入るのか誰かが疑問に思うでしょう。これは、Webアプリで使用される読み取り専用のデータテーブルです。これはでのみインデックス付けされ、idクエリは限られたIDのセットでのみ（このテーブルでの範囲クエリはありません）、列で結合し、id列で直接クエリを実行しidます。テーブルは大規模なHadoopジョブで更新され、効率を上げるためにmysqlimportで毎晩更新されます。
更新：MySQLは70GBのインポート後に最終的にクラッシュしましたが、エラーログにはあまり表示されません。テーブルをmyisamエンジンに変更し、インポートを再試行しています。
