Piwik's disk usage shot up since 2.14.0


Ever since we upgraded to 2.14.0 (we’re now on .2), the disk usage of the piwik database has shot up dramatically. Previously it was growing at about 6GB per month; since the upgrade it’s now at almost 9GB per WEEK.

No other changes were made when Piwik was upgraded. Archiving is done via cron running hourly.

Is this significant increase in disk usage to be expected, or is there a bug here? If it’s a bug, do you have any suggestions on how I can help to track it down?
If it’s not a bug, is there any way we can reduce the rate at which this data is growing?


Hi there,

Feel free to try again installing with the latest 2.15.0 beta version which includes many fixes and improvements, see: I would like to test early beta and RC releases, how do I enable automatic updates to use these development versions? - Analytics Platform - Matomo
