Question

I have a myisam only dedicated 32 GB RAM mysql server that is running on default configuration. I want to change the engine type to InnoDB of one table in order to avoid table locks. It has 50 million records and size on disk is around 15 GB. I am using mysql version 5.5
I guess I will need to add the following options and restart mysql.

innodb_buffer_pool_size=1G
innodb_log_file_size=100M
innodb_file_per_table=1

What else is considered to be necessary while changing the engine type?

Answer 1

You’ll actually be running a command to convert each table.

It goes faster to first sort the table:

ALTER TABLE tablename ORDER BY primary_key_column;

Then, run the alter command:

ALTER TABLE tablename ENGINE = INNODB;

It might take a while if the table is really large, and it will use a lot of your CPU….
