Comparison of Storage Engine Features
Comparison of Storage Engine Features
In this tutorial, we will compare storage engine features. MySQL works with many storage engines to cater the needs of different applications. However, we will stick to common storage engines and a brief comparison of the features in this post.
Common Storage Engines
The most commonly used MySQL storage engines are as follows:
- InnoDB
- MyISAM
- MEMORY
Comparison Chart
Let’s compare some important features of these storage engines.
| InnoDB | MyISAM | MEMORY | |
| Purpose | Supports Transactions and Foreign Keys.
Transactional storage engine with COMMIT/ROLLBACK |
Supports Fast retrievals and applications with few updates.
|
In MEMORY data tables. |
| Usage | Fully ACID compliant transactions | Fastest for read heavy applications | In-memory storage |
| Locking | Row-level locking, Multi-versioning | Table-level locking
Large-grain table locks, no non-locking reads |
Large grain table locks |
| Durability | Durability recovery | Table recovery | No persistence or Disk I/O. Data is lost if the MySQL Server shuts down. |
| Indexing | B-tree indexes | B-tree/Full text/R-tree | Hash/B-tree indexes |
