# 表エンジン {#table_engines}
のテーブルエンジン型式の表を行います。:
2020-04-04 09:15:31 +00:00
- データの格納方法と場所、データの書き込み先、およびデータの読み取り先。
- サポートされているクエリと方法。
2020-04-04 09:15:31 +00:00
- 同時データアクセス。
- インデックスが存在する場合の使用。
- マルチスレッド要求の実行が可能かどうか。
2020-04-04 09:15:31 +00:00
- データ複製パラメーター。
## エンジン家族 {#engine-families}
### メルゲツリー {#mergetree}
2020-04-04 09:15:31 +00:00
高負荷仕事のための最も普遍的な、機能テーブルエンジン。 本物件の共有によるこれらのエンジンには迅速にデータを挿入とその後のバックグラウンドデータを処となります。 `MergeTree` 家族のエンジンの支援データレプリケーション( [複製\*](mergetree-family/replication.md#table_engines-replication) バージョンのエンジン)分割、その他の機能で対応していないその他のエンジンです。

### ログ {#log}
軽量 [エンジン](log-family/index.md) 最低の機能性を使って。 多くの小さなテーブル最大約1万行をすばやく書き込み、後で全体として読み込む必要がある場合に最も効果的です。

## 仮想列 {#table_engines-virtual_columns}
2020-04-04 09:15:31 +00:00
仮想列は、エンジンのソースコードで定義されている整数テーブルエンジン属性です。
2020-04-04 09:15:31 +00:00
仮想列を指定するべきではありません。 `CREATE TABLE` あなたはそれらを見ることができません `SHOW CREATE TABLE``DESCRIBE TABLE` クエリ結果。 仮想列も読み取り専用であるため、仮想列にデータを挿入することはできません。
2020-04-04 09:15:31 +00:00
仮想列からデータを選択するには、仮想列の名前を指定する必要があります。 `SELECT` クエリ。 `SELECT *` 仮想列から値を返しません。
2020-04-04 09:15:31 +00:00
テーブル仮想列のいずれかと同じ名前の列を持つテーブルを作成すると、仮想列にアクセスできなくなります。 これはお勧めしません。 競合を避けるために、仮想列名には通常、アンダースコアが付けられます。
