How to Prevent MySQL Import Timeouts for Large Databases?

Preventing MySQL Import Timeouts for Large Databases

When importing large MySQL dumps, it's common to encounter timeout errors due to extended execution times. To address this, various strategies can be employed:

PHPMyAdmin Import Optimization

If feasible, try using PHPMyAdmin for the import. Increase database import settings in the my.ini file, such as max_allowed_packet and read_buffer_size. Consider raising PHP settings in PHP.ini as well, particularly max_execution_time, max_input_time, and memory_limit.

Big Dump Staged Import

If PHPMyAdmin proves ineffective, utilize Ozerov.de's Big Dump script. This script breaks down large imports into smaller, more manageable blocks, preventing timeouts. Position the SQL dump and script on the server and configure as needed. However, note that Big Dump does not support MySQL exports with extended inserts.

MySQL Console Import

For direct command-line importing, use the MySQL console. First, specify the target database using the use command: use my_great_database;. Then, import the SQL dump using the source command: source C:sqlmy_import.sql;. Allow the import to complete without prematurely closing the console.

MySQL Workbench Import

Consider MySQL Workbench as an alternative import tool, offering a user-friendly interface for large database management tasks.
