Disabling Indexes for Bulk Inserts in InnoDB

In an attempt to optimize bulk insert performance in InnoDB, one may consider temporarily disabling indexes. However, this action triggers a warning message indicating the incompatibility of this option with InnoDB.

Alternatives to Index Disabling for Bulk Inserts:

To circumvent the limitations of index disabling in InnoDB, alternative approaches exist:

  • Suspend Autocommit: Deactivating autocommit (SET autocommit=0) allows for multiple inserts to be grouped into a single transaction, reducing overhead.
  • Disable Unique and Foreign Key Checks: Temporarily disabling unique and foreign key checks (SET unique_checks=0; SET foreign_key_checks=0;) eliminates the need for index lookups during insert operations.
  • Bulk Insert using LOAD DATA INFILE: The LOAD DATA INFILE command bypasses the index, enabling direct data loading into the table.

Additional Tips for Speeding Up Bulk Inserts:

Beyond index disabling, several additional techniques can enhance bulk insert speed:

  • Optimize Table Definition: Define columns with appropriate data types and sizes, reducing unnecessary data conversions.
  • Buffer Pool Tuning: Ensure sufficient buffer pool size to accommodate the entire table data, preventing frequent disk accesses.
  • Batch Inserts: Bundle multiple inserts into a single query, reducing server-client interactions and improving efficiency.
  • Disable Triggers and Stored Procedures: Suspend any triggers or stored procedures associated with the table, eliminating additional processing overhead.
