Which nodes will be inserted into the data-CodePudding

The elastic cluster node I built has a separate data role master role coordinate role ingest role. I also configured the ingest pipeline, which nodes I will pass through when I insert data. The exposed cluster link is the coordinate address

Below is my ingest pipline configuration

PUT _ingest/pipeline/dataocean-timestamp-pipeline
{
  "description": "Adds a field to a document with the time of ingestion",
  "processors": [
    {
    "set": {
      "field": "@timestamp",
      "override": false,
      "ignore_empty_value": true,
      "ignore_failure": true,
      "value": "{{_ingest.timestamp}}"
      }
    }
  ]
}

coordinate to ingest to data or other

Which nodes the correct data flows through Does the official website have these architecture explanations?

CodePudding user response：

If a pipeline is specified in your indexing request, then the document will first be routed to a node that has ingest role.

The pipeline will be executed on that node first, and then, when the document has been processed by the pipeline, it will be sent to a data node that hosts the shard where the document is supposed to be stored (according to its ID hash).

master nodes do not handle indexing requests and coordinating nodes are meant for search requests.

However, if you cluster has a single node that has all those roles, everything will happen on that node, of course.
