What is the Elasticsearch-py equivalent to alias actions?

Question

I am trying to implement multiples indices approach using elasticsearch-dsl. There are basically two steps:

1. Create aliases:

PUT /twee         


        

Answer 1

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
                    }
                }
            }
        )

Answer 2

To implement that you need to use 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"  }}  
  ]
})
