What Does the Value i for node.roles Mean for Nodes in an Elasticsearch Cluster of CSS?

Function

If the value of node.roles of a client node is i, then is this client node an ingest node?

Are there coordinating only nodes in clusters? Are the client requests distributed to coordinating nodes?
Are ingest nodes in 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.
