Compute nodes are compute-only nodes that can be applied to scenarios including stream computing, distributed computing, machine learning, and more. Compute nodes do not store data, so you cannot create databases and tables on this node, but you can load the data for computation by calling the loadTable function.

The compute node is set in the cluster.nodes configuration file as shown below, and the mode setting of node2 to computenode means that node2 is a compute node

localSite,mode
localhost:8901:agent1,agent
localhost:8902:node1,datanode
localhost:8903:node2,computenode

The community license limits the use of a maximum of 3 nodes, that is, one control node, and a maximum of 2 data nodes or compute nodes.
