Coord Node

Concept

Coord node is a kind of logical node, which stores information except user data information.

Coord node is the coordinator of data requests, which merely send requests to relative data nodes rather than takes part in data execution.

Generally, the process of executing coord node is as follow:

  • get a request
  • analyze the request
  • find cooresponding information of the request in local cache
  • if not found, find it in catalogue nodes
  • send the request to corresponding data node
  • get result from data node
  • collect results and send them to client

Coord node contacts with other nodes mainly through catalog service port(shardname parameter).
