Calculate innodb_buffer_pool_size for MySQL

article #1280, updated 20 days ago

Run this query:

SELECT CEILING(Total_InnoDB_Bytes*1.6/POWER(1024,3)) RIBPS FROM 
(SELECT SUM(data_length+index_length) Total_InnoDB_Bytes
FROM information_schema.tables WHERE engine='InnoDB') A;

and use the result it gives, i.e., 4 equals 4G. This and lots more great info here:
