Tdengine Database Fundamentals Explained

Other than the schema for metrics, it also features the schema for tags (static characteristics to get a time-sequence). When creating a desk, application shall use a Steady as template and assign the worth to each tag. Basically, the table is related to a list of tags. For aggregation, the tags is going to be used to be a filter to get the set of tables which shall be scanned for question. It may possibly improve the aggregation significantly.
