Piwik archive tables

General questions
1

Hello,

the database of my Magento 1.9 store contains lots of tables like “piwik_archive_blob_2017_05”, one for each month. Is this where die archive data is stored? So can I drop some of these tables if I don’t need the archive data (from 2016 for example)?

Hi, you can find information about removing old archives in Piwik here:

I wouldn’t recommend manually dropping those tables.
