Disabling Index for Optimized Bulk Inserts in InnoDB

While attempting to disable indexes in an InnoDB table to enhance bulk insert performance, you might encounter a warning due to the absence of this feature in InnoDB's storage engine. Here are alternative strategies to achieve your objective:

MySQL Reference Recommendations:

As suggested by MySQL documentation, consider using the following commands:

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

These commands can be found in the "Bulk Data Loading Tips" section of the MySQL References guide (8.0 version):

Additional Tips for Speeding Up Bulk Inserts:

  • Use LOAD DATA INFILE: This method is specifically designed for bulk loading data into tables and can significantly accelerate the process.
  • Commit Gradually: Committing after every few inserts can reduce the time spent on large transactions.
  • Optimize Table Structure: Ensure that the table has an appropriate index strategy and data type selection to minimize index lookups.
  • Partition Tables: Divide large tables into smaller partitions to optimize data access and insert performance.
