Questions and Answers

26.2.1: Where can I obtain complete documentation for MySQL storage engines and the pluggable storage engine architecture?

See 章 13. ストレージエンジンとテーブルタイプ. That chapter contains information about all MySQL storage engines except for the NDB storage engine used for MySQL Cluster; NDB is covered in 章 14. MySQL Cluster.

26.2.2: Are there any new storage engines in MySQL 5.1?

MySQL 5.1 introduces an alpha version of the new Falcon storage engine.

Falconのサポートは、MySQL5.1の標準リリースではできません。FalconはMySQL 5.1の開発から特別に分岐したリリースにおいてのみ可能です。情報はここで評価のみの目的として供給されます。

For information about the Falcon storage engine, see The Falcon Storage Engine.

There have also been significant improvements in existing storage engines, in particular for the NDB storage engine that forms the basis for MySQL Cluster.

26.2.3: Have any storage engines been removed in MySQL 5.1?

Yes. MySQL 5.1 no longer supports the BDB storage engine. Any existing BDB tables should be converted to another storage engine before upgrading to MySQL 5.1.

26.2.4: What are the unique benefits of the ARCHIVE storage engine?

The ARCHIVE storage engine is ideally suited for storing large amounts of data without indexes; it has a very small footprint, and performs selects using table scans. See 項13.10. 「ARCHIVE ストレージエンジン」, for details.

26.2.5: Do the new features in MySQL 5.1 apply to all storage engines?

The general new features such as views, stored procedures, triggers, INFORMATION_SCHEMA, precision math (DECIMAL column type), and the BIT column type, apply to all storage engines. There are also additions and changes for specific storage engines.
