In MySQL, you can set the size of tablespace in the following way:

  1. Adjust the storage engine and table space size of a table using the ALTER TABLE command. For example, you can set the storage engine of a table to InnoDB and adjust the table space size with the following command.
ALTER TABLE table_name ENGINE=InnoDB, ALGORITHM=COPY;
  1. When creating a table, you can set the tablespace size in the CREATE TABLE statement. For example, you can create an InnoDB table and specify the tablespace size with the following command:
CREATE TABLE table_name (
    ...
) ENGINE=InnoDB
ROW_FORMAT=COMPRESSED
KEY_BLOCK_SIZE=8
DATA DIRECTORY='/path/to/table/space';
  1. Set the default tablespace size in the configuration file my.cnf. You can specify the size of the InnoDB tablespace by setting the innodb_data_file_path parameter in the configuration file.
innodb_data_file_path = ibdata1:10M:autoextend

Please be cautious when adjusting the size of the table space to avoid impacting the data. It is recommended to first back up the data before proceeding with the operation.
