什么是 Elasticsearch-py 等同于别名操作？

Question

我正在尝试实施 multiples indices approach using elasticsearch-dsl。基本上有两个步骤：

1.创建别名：

PUT /tweets_1/_alias/tweets_search 
PUT /tweets_1/_alias/tweets_index

2。必要时更改别名：

POST /_aliases
{
  "actions": [
    { "add":    { "index": "tweets_2", "alias": "tweets_search" }}, 
    { "remove": { "index": "tweets_1", "alias": "tweets_index"  }}, 
    { "add":    { "index": "tweets_2", "alias": "tweets_index"  }}  
  ]
}

我只能使用 elasticsearch-py（不是 dsl）来实现第 1 步：

from elasticsearch.client import IndicesClient
IndicesClient(client).("tweets_1", "tweets_search")
IndicesClient(client).("tweets_1", "tweets_index")

我不知道如何为第 2 步执行此操作。那么，elasticsearch-dsl（或至少在 elasticsearch-py）中的等价物是什么？

Answer 1

要实现，您需要使用 elasticsearch-py:

from elasticsearch import Elasticsearch
es = Elasticsearch()

# use es.indices instead of instantiating IndicesClient
es.indices.put_alias(index='tweets_1', name='tweets_search')
es.indices.put_alias(index='tweets_1', name='tweets_index')

es.indices.update_aliases({
  "actions": [
    { "add":    { "index": "tweets_2", "alias": "tweets_search" }}, 
    { "remove": { "index": "tweets_1", "alias": "tweets_index"  }}, 
    { "add":    { "index": "tweets_2", "alias": "tweets_index"  }}  
  ]
})

Answer 2

index_list_for_realias = [...]
aliases_list_to_realias = [...]

for i in index_list_for_realias:
    print(i)
    for j in aliases_list_to_realias:
        es.indices.put_alias(index=i, name="logstash5-uni-" + j, body={
                "filter": {
                    "term": {
                        "uni": j
                    }
                }
            }
        )
