什麼是Elasticsearch-py等效於別名操作？

Question

我正在嘗試使用elasticsearch-dsl執行multiples indices的方法。基本上有兩個步驟：

1.創建別名：

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

2.更改別名必要時：

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

我只能實現使用elasticsearch-py步驟1（不是dsl）：

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

我不知道如何做第2步。那麼，在elasticsearch-dsl（或者至少在elasticsearch-py）中等價呢？

Answer 1

要實現，你需要使用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" }} 
    ] 
})
