One, MySQL storage engine
1.1 What storage engines are available
The MySQL storage engine includes the engine that handles transaction security tables and the engine that handles non-transactional security tables.
1
Transaction Security Table engine
2
Non-transactional security table engine
- MyISAM, MERGE, MEMORY (HEAP), EXAMPLE, Federated, ARCHIVE, CSV, Blackhole.
1.2 How do I choose the most suitable storage engine for you? MyISAM: The default MySQL plug-in storage engine, which is one of the most commonly used MySQL storage engines in the Web, data warehousing, and other application environments.
InnoDB: For transactional applications, with many features, including acid transaction support.
BDB: An alternative to the INNODB transaction engine that supports commit, rollback, and other transactional features.
Memory: Keep all your data in RAM and provide extremely fast access in environments where you need to quickly find references and other similar data.
Merge: Allows a MySQL DBA or developer to logically group together a series of equivalent MyISAM tables and reference them as 1 objects. Ideal for VLDB environments such as data warehousing.
Archive: Provides the perfect solution for storing and retrieving large amounts of historically, archived, or security audit information that is rarely referenced.
Federated: The ability to link multiple separate MySQL servers to create a logical database from multiple physical servers. Ideal for distributed environments or data mart environments.
Cluster/ndb:mysql's clustered database engine, especially suitable for applications with high performance lookup requirements, also requires the highest uptime and availability.
Other: The other storage engines include CSV (referencing a comma-delimited file used as a database table), blackhole (for temporary suppression of application input to the database), and the example engine, which can help with the quick creation of a custom plug-in storage engine.
