[[outputs.iotdb]]
  ## Configuration of IoTDB server connection
  host = &quot;127.0.0.1&quot;
  # port = &quot;6667&quot;

  ## Configuration of authentication
  # user = &quot;root&quot;
  # password = &quot;root&quot;

  ## Timeout to open a new session.
  ## A value of zero means no timeout.
  # timeout = &quot;5s&quot;

  ## Configuration of type conversion for 64-bit unsigned int
  ## IoTDB currently DOES NOT support unsigned integers (version 13.x).
  ## 32-bit unsigned integers are safely converted into 64-bit signed integers by the plugin,
  ## however, this is not true for 64-bit values in general as overflows may occur.
  ## The following setting allows to specify the handling of 64-bit unsigned integers.
  ## Available values are:
  ##   - &quot;int64&quot;       --  convert to 64-bit signed integers and accept overflows
  ##   - &quot;int64_clip&quot;  --  convert to 64-bit signed integers and clip the values on overflow to 9,223,372,036,854,775,807
  ##   - &quot;text&quot;        --  convert to the string representation of the value
  # uint64_conversion = &quot;int64_clip&quot;

  ## Configuration of TimeStamp
  ## TimeStamp is always saved in 64bits int. timestamp_precision specifies the unit of timestamp.
  ## Available value:
  ## &quot;second&quot;, &quot;millisecond&quot;, &quot;microsecond&quot;, &quot;nanosecond&quot;(default)
  timestamp_precision = &quot;millisecond&quot;

  ## Handling of tags
  ## Tags are not fully supported by IoTDB.
  ## A guide with suggestions on how to handle tags can be found here:
  ##     https://iotdb.apache.org/UserGuide/Master/API/InfluxDB-Protocol.html
  ##
  ## Available values are:
  ##   - &quot;fields&quot;     --  convert tags to fields in the measurement
  ##   - &quot;device_id&quot;  --  attach tags to the device ID
  ##
  ## For Example, a metric named &quot;root.sg.device&quot; with the tags `tag1: &quot;private&quot;`  and  `tag2: &quot;working&quot;` and
  ##  fields `s1: 100`  and `s2: &quot;hello&quot;` will result in the following representations in IoTDB
  ##   - &quot;fields&quot;     --  root.sg.device, s1=100, s2=&quot;hello&quot;, tag1=&quot;private&quot;, tag2=&quot;working&quot;
  ##   - &quot;device_id&quot;  --  root.sg.device.private.working, s1=100, s2=&quot;hello&quot;
  convert_tags_to = &quot;fields&quot;
