What are the differences between MyISAM and InnoDB?

InnoDB vs MyISAM InnoDB has row-level locking. MyISAM only has full table-level locking. InnoDB has what is called referential integrity which involves supporting foreign keys (RDBMS) and relationship constraints, MyISAM does not (DMBS). InnoDB supports transactions, which means you can commit and roll back.

What are the advantages of MyISAM over InnoDB?

– MyISAM is faster than InnoDB in most of the cases. – MyISAM table is stored as a separate file which can be compressed. – This means that MyISAM has a better storage management. – MyISAM supports full indexing that is not supported by InnoDb.

Should I use InnoDB or MyISAM?

InnoDB can be used for row level locking, that means it gives higher performance as compared to MyISAM. InnoDB can be used for both data and index for a large buffer pool. InnoDB can be used when we need better performance than MyISAM.

Why u should go for MyISAM?

MyISAM is an ideal choice if you are new to MySQL, your web application is simple, has to be fast, or use full-text searches. However, it should not be used when data integrity is a priority. Possible applications could include content management systems, online bookmarking tools, RSS readers, or simple search engines.

How does InnoDB work?

InnoDB tables arrange your data on disk to optimize queries based on primary keys. Each InnoDB table has a primary key index called the clustered index that organizes the data to minimize I/O for primary key lookups. See Section 14.6. To maintain data integrity, InnoDB supports FOREIGN KEY constraints.

How do I know if my database is MyISAM?

To check a MyISAM table, use the following commands:

  1. myisamchk tbl_name. This finds 99.99\% of all errors.
  2. myisamchk -m tbl_name. This finds 99.999\% of all errors.
  3. myisamchk -e tbl_name. This does a complete and thorough check of all data ( -e means “extended check”).
  4. myisamchk -e -i tbl_name.
