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.
