Rebuilding Indexes and Updating Stats in MySQL InnoDB

For database administrators accustomed to MS SQL server, the question arises: Does MySQL offer similar capabilities for rebuilding indexes and updating statistics within its InnoDB storage engine?

Answer: MySQL's Approach to Index Maintenance and Statistics

Unlike MS SQL server, MySQL InnoDB does not provide an explicit "rebuild index" option. Instead, it automatically adjusts its indexes as data changes. Every UPDATE and INSERT operation includes an implicit update of index statistics.

To further enhance performance, MySQL relies on the ANALYZE TABLE statement.

Using the ANALYZE TABLE Statement

The ANALYZE TABLE command gathers key distribution information for a specified table. This information is crucial for creating efficient execution plans. By locking the table with a read lock during analysis, MySQL ensures accuracy and consistency.

Example:

ANALYZE TABLE table_name;
