Hi,
I duplicated the database before the upgrade. Everything went fine, but by simply copying the database, it's getting bigger every time. As an example, our database was 640 MB before copy, the copy version with exactly the same data is now 1.55 GB.
2 tables seems to be mainly affected, see below :
Before :
rv_data_summary_ad_hourly - 814 639 entries - 128.3 MB
rv_data_summary_ad_zone_assoc - 1 604 550 entries - 342.6 MB
After :
rv_data_summary_ad_hourly - 2 307 907 entries - 366.5 MB
rv_data_summary_ad_zone_assoc - 3 568 792 entries - 804 MB
It occurs during every update, over time it will go to disaster
any idea why this happens and how to clean those two tables ?
