Does the Value i of node.roles Indicate an Injest Node?

Function

If the value of node.roles of a client node is i, then is this client node an injest node?
  • Are there coordinating only nodes in clusters? Are the client requests distributed to coordinating nodes?
  • Are ingest nodes in the idle state when there are no ingest requests?

Solution

If the value of node.roles of a client node is i, the ingest node mode is enabled.

  • The coordinating only nodes of Elasticsearch are called client nodes in CSS. If a cluster has no client nodes, client requests will be distributed to all nodes.
  • An ingest node functions as a set of ELK for data conversion. If there is no ingest requests, ingest nodes are not in the idle state.
