Thread:Project:Support desk/DB Size continously increasing since upgrade from 1.17 to 1.19/reply

There are some caches inside the DB, e.g. one is the table object_cache. If you want to you can TRUNCATE this table, however, this will empty that cache and so destroy the performance increase, which it brings.

However, I would not care about some MBs in the DB too much. MySQL is made to work with much bigger amounts, even with gigabytes of data; if you have some ridiculuous MB more or less should not matter. ;-)
