Managing indices

In the previous recipe we saw how to initialize a client to send calls to an ElasticSearch cluster. In this recipe, we will see how to manage indices via client calls.

Getting ready

You need a working ElasticSearch cluster and required packages of the Creating a client recipe of this chapter.

The full code of this recipe is in the chapter_11/indices_management.py file.

How to do it...

In Python, managing the lifecycle of your indices is very easy, we need to perform the following steps:

1. We initialize a client as follows:

   import elasticsearch
   es = elasticsearch.Elasticsearch()
   index_name = "my_index"

2. All the indices methods are available in the client.indices namespace. We can create and wait for the creation of an index as follows:

   es.indices.create(index_name)
   es.cluster.health(wait_for_status="yellow")

3. We can close/open an index as follows:

   es.indices.close(index_name)
   
   es.indices.open(index_name)
   es.cluster.health(wait_for_status="yellow")

4. We can optimize...
