We have created a ticket in the past saying we can't increase the MaxFileSize for Integrate greater than 2 GB. We have been told that this column in hvr repository is defined as int, so it doesn't support more than 2 GB but we have been told that they will look into adding in the next 5.7.5 release. So wondering if there is any plan to fix this in 5.7.x release. 

We can take a downtime to alter the column to change it from int to bigint if needed. So, please let us know if a fix can be delivered as soon as possible. We don't want to set that as unlimited as it carries some risk on sending a very large file, if we pause integration for some time.
