I am running Drupal Commons 6.x25 (released February 2012); I have installed it yesterday locally on a lamp, on OpenSuse 12.1. Now I want to move it to the web server, but I have noticed that the fresh database—without any special module, beside the ones that are shipped with commons—is extremely large (16 Mbit).
Sometimes, the moving of a database can be too hard since the database is a way too large. Which Drupal tables are safe to manually clear using PhpMyAdmin?
What about all the "cache_" prefixed tables be emptied without causing problems?
Background: well - sometimes i have some troubles in meging the 16 db at once... but i continue to try to move a drupal-commons in a single step without any emptiying. BTW to which extend we can lower the db-size of 16 mb - 10 or 5 mb probably.
