Even though we are using "innodb_file_per_table = 1" from day one. The ibdata file still continues to grow. Total size of our database is around 800GB and the ibdata file is currently around 50GB. All our tables are innodb.
How can it grow when we use innodb_file_per_table?
Could it be blobs, mediumtext or these kinds of columns?
Is there a way to shrink this considering we already use innodb_file_per_table?
