-### 2.2.1. Permissions
+The system allows exporting directly into [InfluxDB](https://docs.influxdata.com/influxdb) version >= 2.0 or into any system using the [InfluxDb-Line-Protocol](https://docs.influxdata.com/influxdb/v2.1/reference/syntax/line-protocol/) e.g. [QuestDB](https://questdb.io/) over TCP.
+
+As of writing (using InfluxDB v2.1 and using the *flux*-language), the data written by this system was a bit too much for InfluxDB and it struggled very quickly on a fairly beefy machine.
+
+Thats why the additional LineProtocol-Export-Method was added. Freedom of choice of the Time-Database.
+
+<br>
+
+If you want to use the InfluxDB-Line-Protocol, simply set the environment variable `USE_INFLUXDB_LINEPROTOCOL` to `true` along with the-other necessary Host and Port-variables.
