TDengine can be deployed in cluster mode to increase the processing capability and high availability. In cluster mode, any data can have multiple replications for the purpose of high availability and load balance. TDengine cluster can be scaled out easily to support more data collecting points and more data.
TDengine has a native distributed design and provides the ability to scale out. A few of nodes can form a TDengine cluster. If you need to get higher processing power, you just need to add more nodes into the cluster. TDengine uses virtual node technology to virtualize a node into multiple virtual nodes to achieve load balancing. At the same time, TDengine can group virtual nodes on different nodes into virtual node groups, and use the replication mechanism to ensure the high availability of the system. The cluster feature of TDengine is completely open source.
This chapter mainly introduces cluster deployment, maintenance, and how to achieve high availability and load balancing.
