Re: Data length for INNODB tables

if we disable the parameter innodb_file_per_table=OFF, innodb will not free up space after deletion.
i had the similar issue where this paramter was off, so when i was deleting data from any table "data_length" was as it is. No change was there in data_length although there should be.

So i turned this parameter on and restart of mysql process freed up space.

But not sure what will happen if i will delete from any other table now.
