Mysql – How to disable index in innodb

indexinginnodbmysql

I'm trying to speed up bulk insert in an InnoDB table by temporary disabling its indexes:

ALTER TABLE mytable DISABLE KEYS;

But it gives a warning:

+-------+------+-------------------------------------------------------------+
| Level | Code | Message                                                     |
+-------+------+-------------------------------------------------------------+
| Note  | 1031 | Table storage engine for 'mytable' doesn't have this option |
+-------+------+-------------------------------------------------------------+
1 row in set (0.00 sec)

How can we disable the indexes?

What alternatives are there to avoid using the index when doing bulk inserts?

How can we speed up the process?

Best Solution

Have you tried the following?

    SET autocommit=0; 
    SET unique_checks=0; 
    SET foreign_key_checks=0;
