When designing your data model, to ensure system performance and scalability, prioritize creating a large number of devices rather than accumulating an unlimited number of time series under a single device. Simultaneously, ensure that the cardinality of the penultimate node in the path reaches at least 1000 to provide sufficient concurrency granularity, and use suffixes such as .value at the end of the path to clearly identify data points—for example, it is recommended to adopt a high-concurrency model like root.db.device01.metric.value, rather than the inefficient structure of root.db.device01.metric.
