es之pipeline给索引加时间戳_es pipeline

步骤：
1.创建pipeline
PUT _ingest/pipeline/my_timestamp_pipeline
{
  "description": "Adds a field to a document with the time of ingestion",
  "processors": [
    {
      "set": {
        "field": "ingest_timestamp",
        "value": "{{_ingest.timestamp}}"
      }
    }
  ]
}

情况1，新建表加pipeline
PUT test111
{
    "settings": {
      "index":{
        "number_of_shards" :   3,
        "number_of_replicas" : 1,
        "blocks.read_only_allow_delete": "false",
        "default_pipeline": "my_timestamp_pipeline"
      }
    },
  "mappings": {
    "properties": {
      "addbigint1": {
        "type": "long"
      }}}

情况2.给已存在索引加时间戳
PUT /testme/_settings
{
"default_pipeline": "my_timestamp_pipeline" 
}
