Old configuration makes all devices have the same tag.
# 标签名的前缀 # TAG_NAME_PREFIX=tag_ # 定义设备标签值，所有设备相同，使用逗号分开，目前支持iotdb-0.12, iotdb-0.13, influxdb-2.x, timescaledb, tdengine # DEVICE_TAGS=
New configuration automatically generates different tags for different devices. Tags will be generated based on the hash value of the deviceName.
# 标签名数量 # TAG_NUMBER=0 # 标签名前缀 # TAG_KEY_PREFIX=tag_ # 标签值前缀 # TAG_VALUE_PREFIX=value_ # 每个标签值的取值种数，使用逗号分开，设置个数应与标签名数量相等。例如TAG_NUMBER=2，TAG_VALUE_CARDINALITY=50,10，说明第一个标签名可能有50种值，第二个标签名可能有10种值 # TAG_VALUE_CARDINALITY=
For example：
# 25000device # Tags: 品牌, 项目, 车型 TAG_NUMBER=3 TAG_KEY_PREFIX=tag_ TAG_VALUE_PREFIX=value_ TAG_VALUE_CARDINALITY=50,50,10
