consequences of deleting mosquitto.db file?

[tpd-opitz]

I have a strange behavior sending values from teslamate vis MQTT bridge to another system.

For testing I set teslamate/cars/1/battery_state to 76 (the SoC of the car at that time) manually using MQTT Explorer and checking the retention checkbox. I did the same with the respective topic on the other side.

Now once a while the other system shows this random value especially after starting up their MQTT broker (also a mosquitto).
My hope is to get rid of this strange behavior by deleting the mosquitto.db file in both systems.

Is ist save for teslamate operation to delete this file while mosquitto container is stopped?
In other words: does teslamate depend on anything permanently stored in this file?
