Besides the schema for metrics, it also features the schema for tags (static characteristics for just a time-collection). When creating a desk, application shall make use of a Steady as template and assign the worth to every tag. Put simply, the table is connected with a list of tags. For aggregation, the tags will be made use of as a filter to find the list of tables which shall be scanned for query. It could Increase the aggregation significantly.
Partitioning: In combination with sharding the info, TDengine also divides time sequence data stored in the vnode In accordance with time durations. The data of each and every time frame needs to be saved with each other, and the info of various time intervals is not going to overlap. The time frame could be someday or many days, which is described because of the user. Dividing time sequence facts by time period has numerous rewards. When querying information, the file being searched could be immediately located in accordance with the period of time, thereby dashing up the query.

Retain: specifies enough time for which information is retained. Enter a worth in between 1 and 365000. The default value is 3650. The value from the KEEP parameter have to be increased than or equal to the worth from the DURATION parameter. TDengine immediately deletes facts which is more mature than the worth in the KEEP parameter.
