Hi all,

I have a prestashop instance hosted on OVH.

The plan is cheap and the database is little and after a while the db is full.

I launch that query to finds out heaviest table on mysql:

SELECT 
     table_schema as `Database`, 
     table_name AS `Table`, 
     round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB` 
FROM information_schema.TABLES 
ORDER BY (data_length + index_length) DESC;

here the result of the query

mod140_guest                336.42
mod140_connections          334.47
mod140_connections_source   13.53
mod140_cart                 0.84
...

I do not know so well Prestashop database, I google for that tables on Google but I do not find so much infos...

I would like to delete some data from database to free up space and keep the actual plan

Can someone help me?
