Troubleshooting Tips: MySQL ibdata1 file too big

The ibdata1 file can be described as a system tablespace for the InnoDB infrastructure. Furthermore, it consists of different classes for information that is crucial for InnoDB. Enabling the innodb_file_per_table allows the tables to be stored in their own tablespace.

However, the shared tablespace consists of internal data of other InnoDBs.

• Data dictionary
• Doublewrite buffer
• Change buffer
• Undo logs

According to our Support Team, we can track down the reason behind a rapidly growing idbdata1 file with the following command:

SHOW ENGINE INNODB STATUSG
