I was trying to optimize the InnoDB tables. I have executed the next query to detect what are the fragmented tables.
FROM TABLES WHERE TABLE_SCHEMA NOT IN ("information_schema","mysql") AND Data_free > 0
After that, I have seen that there are 49 fragmented tables. With one table, I have executed "optimize table table_name;" and "analyze table table_name;". The result is the same, the table continuous fragmented.
Any suggestions? I have followed the mysqltuner recommendations...
