The put pipeline API adds pipelines and updates existing pipelines in the cluster.
PUT _ingest/pipeline/my-pipeline-id
{
"description" : "describe pipeline",
"processors" : [
{
"set" : {
"field": "foo",
"value": "bar"
}
}
]
}
The put pipeline API also instructs all ingest nodes to reload their in-memory representation of pipelines, so that pipeline changes take effect immediately.
