ElasticSearch updates are not immediate, how do you wait for ElasticSearch to finish updating it's index?

Question

I\'m attempting to improve performance on a suite that tests against ElasticSearch.

The tests take a long time because Elasticsearch does not update it\'s indexes i

As of version 5.0.0, elasticsearch has an option:

 ?refresh=wait_for

on the Index, Update, Delete, and Bulk api's. This way, the request won't receive a response until the result is visible in ElasticSearch. (Yay!)

See https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-refresh.html for more information.

edit: It seems that this functionality is already part of the latest Python elasticsearch api: https://elasticsearch-py.readthedocs.io/en/master/api.html#elasticsearch.Elasticsearch.index

Change your elasticsearch.update to:

elasticsearch.update(
     index='blog',
     doc_type='blog'
     id=1,
     refresh='wait_for',
     body={
        ....
    }
)

and you shouldn't need any sleep or polling.
