Subject:Re: Reducing ibdata1 file size
View as plain text  
Thanks for the reply, but in my case the datafile is growing 1 GB per day
with only 1 DB (apart from mysql / information_schema / test) and the size
of the DB is just 600MB, where records get updated / deleted / added and on
an average it maintains 600MB only. Now the datafile is increased to 30GB
from the past 30 days, do you have any idea how to reduce this ?

Also just wondering what does the datafile contains actually and why can't
it gets decreased ?

*thanks & regards,
