MySQL

Comparison of Storage Engine Features

Overview

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
