innodb_io_capacityThe basic syntax for this command is innodb_strict_modeThe basic syntax
for this command is innodb_autoinc_lock_modeThe basic syntax for this command is innodb_read_io_threadsUse the innodb_data_file_pathThe basic syntax for this command is The full syntax for a data file is as follows: To get more detailed information, see InnoDB startup options and system variables.
