Inegration, reliability/error handling

Hello everybody,

I couldn’t find this in the documentation, if it is documented somewhere please point me to it.

I wish to ensure, that all data received from a sensor is forwarded by ChirpStack to some kind receiver (e.g. using the integration and PostgreSQL, MQTT or HTTP).
But how would one handle connection errors or receivers that are not able to receive the data at this moment?
Will ChirpStack try to send the missing data at a later time or will the data just be lost?
Is there any kind of error handler one can use to react to such situations?

Best regards,
