Support buffering data while the database is temporarily unavailable

[Minecraft0122]

I would like to be able to..

If Plan can't connect to MySQL for a while, it would be nice if it could cache the collected data locally and sync it after the connection is restored, instead of losing that data.

If possible, making database writes asynchronous would also help prevent the server from stalling while waiting for database operations or reconnection attempts.

Is your feature request related to a problem? Please describe.

My servers use a remote MySQL database. Temporary network issues can happen, and I'd like to avoid losing analytics data because of a short disconnect.

Sidenote that All database connections are async already so server should not stall if database connection is lost.
