Sharding: All information from a single info selection point is stored in only one vnode, however Each and every vnode can retail store the information of several facts selection details. The vnode suppliers some time-collection info and in addition the metadata, such as tags and schema, for the information collection place.

Partitioning: Together with sharding the data, TDengine also divides it by period of time. The data for each period of time is saved collectively, and the information of different time periods can not overlap. This time frame is a configurable worth of a single or a number of days.

each setString and setNString need the user to declare the width of your corresponding column in the size parameter on the table definition

In the above mentioned illustration, JDBC uses the client's configuration file to establish a relationship to the hostname cluster_node1, port 6030, along with a database named check. When the firstEp node within the cluster fails, JDBC tries to connect with the cluster employing secondEp.

Sharding: In the design and implementation of TDengine, a cluster has many nodes, Every node can have a number of virtual nodes (vnode), Every Digital node outlets the information of a certain number of data assortment details, and the information of a knowledge collection point is usually saved in just one vnode. This fashion, if there are many facts collection points, the information from these data collection points are going to be dispersed to several vnodes and distributed in a number of nodes. When information is ingested, the TDengine client instantly writes the info towards the corresponding vnode, thereby achieving horizontal scaling of information ingestion.

TDengine's native JDBC connection implementation has appreciably enhanced its assistance for facts writing (INSERT) scenarios by way of bind interface. Composing knowledge in this way avoids the resource consumption of SQL syntax parsing, causing significant create functionality enhancements in several conditions.
