There is no automatic DB management.
If a DB is over limit, INSERT will fail.
If you delete a device, its records remain.
DB is under your full control and it is your responsibility to vaccum, delete old records, etc.
Thanks for these details - looks like I would have found out the hard way is a short period of time.
Would be great if mDash could implement a threshold alert whereby the owner was notified when the database size was approaching its limit. Far better than having that same owner getting angry calls from his customers when that limit was reached.
I’ve noticed that when executing DELETE SQL command to remove records from the db, the ‘DB Size’ reported by mDash does not change. Is there an expected lag between record removal and an accurate reporting on the ‘Data’ tab?
