AWS RDS MYSQL How do I reduce the DB size?
One idea (wholly un-researched, so there might be a better way, but this should work):


Create a new RDS instance that is smaller in size.
Dump the old one into the new one:

mysqldump -h &lt;old-RDS&gt; -u &lt;user&gt; -p&lt;password&gt; | mysql -h &lt;new-RDS&gt; -u &lt;user&gt; -p&lt;password&gt;

Whack the old one.


Of course, this assumes your total db size is smaller than 20GB, and that you're just looking to end up with a smaller instance. If you're trying to shrink the size of the database, in total, that's a different question.
