Resize MySQL Tablespace: Step-by-Step Guide

The method to resize MySQL table space can be completed through the following steps:

1. To check the current tablespace usage, you can use the following SQL statement to view the tablespace usage of the current MySQL database:

SELECT table_schema AS `Database`, 
  ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS `Size (MB)` 
FROM information_schema.tables 
GROUP BY table_schema;

1. Identifying the tablespaces that need to be resized: Based on the query results from the previous step, determine the database tablespaces that need to be resized.
2. Execute the ALTER TABLE command: You can use the ALTER TABLE command to resize tables, for example:

ALTER TABLE table_name ADD COLUMN column_name INT;

1. Using the ALTER DATABASE command: You can expand a database using the ALTER DATABASE command, for example:

ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

1. Increasing disk space: If increasing the table space is still not enough, consider adding more disk space to solve the issue. You can add space to the existing disk or add space to another disk and migrate the database to the new disk.
2. Restart the MySQL service: After expanding the tablespace, it is necessary to restart the MySQL service for the changes to take effect.

The above are the brief steps for expanding MySQL table space. The specific operations can be adjusted according to actual circumstances.
