Common Storage Engines

The most commonly used MySQL storage engines are as follows:

  • InnoDB
  • MyISAM
  • MEMORY

Let’s compare some important features of these storage engines.

InnoDBMyISAMMEMORY
PurposeSupports Transactions and Foreign Keys.

Transactional storage engine with COMMIT/ROLLBACK

Supports Fast retrievals and applications with few updates.

 

In MEMORY data tables.
UsageFully ACID compliant transactionsFastest for read heavy applicationsIn-memory storage
LockingRow-level locking, Multi-versioningTable-level locking

Large-grain table locks, no non-locking reads

Large grain table locks
DurabilityDurability recoveryTable recoveryNo persistence or Disk I/O. Data is lost if the MySQL Server shuts down.
