The mysqldump utility is a free software allowing “logical” backup of any MySQL database by saving it to a text sequence of SQL queries. Originally developed by Igor Romanenko at 1999, now it grows to one of main functional utilities of MySQL environment.

The resulting file created by mysqldump, a database dump, contains the SQL statements needed to build the database from scratch. These statements are independent from the original database. Executing this sequence will restore the database, e.g. for MySQL replication.

Experiments with MySQLDump Backups

The main advantage of dump files created with mysqldump is that they have a very simple and readable internal format. A user can rewrite these dump files manually as it needed, which makes dumps a perfect source for experiments.

Sample Experiment Setup

For example, let you have a MySQL database with multiple tables, and an application (e.g. a web server) working with it. Each table can use its individual storage engine.

Two key factors define the performance of your application:

  • How the data objects are distributed throughout the database;
  • How the database retrieves and stores information.

That is what database architecture design is about.

Modify files created by mysqldump

Files created by mysqldump can be modified with any text editor, which makes it really easy to test different combinations of storage engines, and find out what works for you. Moreover, it also enables you to prepare a plan on how to deal with future database load. The plan is as follows:

  1. Create a backup of your MySQL database. You can do it with mysqldump, or through the MySQL Backup feature of Handy Backup.
  2. Prepare a testing environment that enables you to simulate different database loads and measure the application’s response time.
  3. Modify the dump files by changing storage engines used in tables. To do it, find the CREATE TABLE statements and add ENGINE=MyISAM or ENGINE=InnoDB to them.
  4. Restore the database with the use of the modified MySQL dump files. Run the tests.
  5. Repeat steps 3-4 with different combinations of storage engines.
  6. When you finish, roll the database to the original state.
  7. Analyze the results.

Migrating to Some Different DBMS

Another scenario in which dump files created by mysqldump or Handy Backup can be useful is migration from MySQL to other database management systems. All popular DBMS aim to comply with the SQL standard, with only some minor changes required for a typical dump file.

To see if you can transfer your MySQL data to another DBMS, you can simply make a dump and try to restore it to a different system. You can read main recommendations on performing this task on the MySQL Recovery page.
