StatefulSet instead of Deployment

[thedmi]

Is there a specific reason why the influxdb chart uses a Deployment instead of a StatefulSet? If I understand correctly, this means that two pods will share the same PV for a short amount of time during pod reschedules (e.g. updates, node drains).

Is InfluxDB able to handle concurrent R/W access to data files from multiple instances? If so, a Deployment probably works fine. If not, this may be a serious possibility for data corruption and a StatefulSet would be the only right choice here.
