Disable Indexing for Speedy Bulk Inserts in InnoDB

When performing bulk data loading into an InnoDB table, a fleeting suspension of indexes can lead to significant performance gains. However, executing the command "ALTER TABLE mytable DISABLE KEYS" often encounters the warning, "Table storage engine for 'mytable' doesn't have this option."

Alternative Methods to Disable Indexing

To circumvent the limitation of the "DISABLE KEYS" command, consider these alternative approaches:

• Disable Autocommit, Key Checks, and Foreign Key Checks: Execute the following commands:

SET autocommit=0;
SET unique_checks=0;
SET foreign_key_checks=0;

This will instruct MySQL to postpone the execution of transactions, deactivating index-driven uniqueness and referential integrity checks during bulk inserts.

• DROP and Recreate Indexes: Remove the existing indexes, perform the bulk insert, and then create the indexes again. This approach is effective but labor-intensive if you have numerous indexes on the table.

Speeding Up the Bulk Insert Process

In addition to disabling indexing, consider these additional tips for optimizing bulk data loading:

• Use the LOAD DATA INFILE Command: This dedicated command is specifically designed for large-scale data imports.
• Disable InnoDB Buffer Pool: By suspending the buffer pool, MySQL can allocate more memory to handle large transactions.
• Increase the Key Buffer Size: A larger key buffer size allows MySQL to cache more indexes, potentially improving performance for subsequent queries after the bulk insert.

By implementing these strategies, you can significantly accelerate bulk insert operations in InnoDB while maintaining data integrity and reducing unnecessary overhead.
