Uploading keepass database to the cloud?

Is it insecure to upload Keepass database to Google Drive, Dropbox or any other file service in the cloud?

I've read this answer in Security Stackexchange: https://security.stackexchange.com/a/45337

So, I feel kinda confident if a put a big number of PBKDF2 iterations, like 10.000.000, it should be OK.

My master password is based on diceware, but is not very very long because I need to remember it.

What do you people think about this?
