After enabled badger, the vlog file up to 700M one day and 4GB one week

This is too big for my tiny server.

I want keep the lefted message to restore after shutdown server, but this size if far out of my expectations.

Why it is so big? And how to reduce it? (it might about badger but stores what messages left to users who use it, so post the issue here)
