MySQL 5.7 not accepting values of innodb_buffer_pool_instances greater than 1 I've been tweaking the values of the buffer pool size (innodb_buffer_pool_size) and the number of buffer pool instances (innodb_buffer_pool_instances) in the my.ini initialization file to optimize heavy load handling with MySQL. I can successfully change the buffer pool size, both dynamically and with the my.ini file, but no matter what I change the innodb_buffer_pool_instances value to, it is always 1 when I query it with SELECT @@innodb_buffer_pool_instances;

What I've already tried:


I made sure to set the buffer pool size > 1GB. I've set it to 24GB and verified that it is indeed that big.
Made sure I'm using the correct my.ini file location.
After changing the value in my.ini I restart the MySQL server.
I've even tried restarting my computer after changing the value, but it still always remains 1.


What am I missing? Why can't I change the value of innodb_buffer_pool_instances?
Fixed it. I just reinstalled MySQL and now the variable updates just like it should. Don't know why it wasn't working, but I don't really care since it works now.
