Elasticsearch映射-重命名现有字段

您可以通过创建一个Ingest管道来做到这一点，该管道包含一个Rename
Processor
和Reindex
API
。

PUT _ingest/pipeline/my_rename_pipeline{  "description" : "describe pipeline",  "processors" : [    {      "rename": {        "field": "fieldCamelcase",        "target_field": "fieldCamelCase"      }    }  ]}POST _reindex{  "source": {    "index": "source"  },  "dest": {    "index": "dest",    "pipeline": "my_rename_pipeline"  }}

请注意，您需要运行Elasticsearch 5.x才能使用摄取。如果您运行的是<5.x，那么您必须使用他评论中提到的@Val :)
