python - Connection Timeout with Elasticsearch

Question

from datetime import datetime
from elasticsearch import Elasticsearch
es = Elasticsearch()

doc = {
    'author': 'kimchy',
    'text': 'Elasticsearch: cool. bonsai cool.',
    'timestamp': datetime(2010, 10, 10, 10, 10, 10)
}
res = es.index(index="test-index", doc_type='tweet', id=1, body=doc)
print(res['created'])

This simples code is returning the following error:

elasticsearch.exceptions.ConnectionTimeout: ConnectionTimeout caused by - ReadTimeoutError(HTTPConnectionPool(host='localhost', port=9200): Read timed out. (read timeout=10))

Very strange, because the server is ready and set (http://localhost:9200/ is returning some json).

Answer 1

By default, the timeout value is set to 10 secs. If one wants to change the global timeout value, this can be achieved by setting the flag timeout=your-time while creating the object.

If you have already created the object without specifying the timeout value, then you can set the timeout value for particular request by using request_timeout=your-time flag in the query.

es.search(index="my_index",
          doc_type="document",
          body=get_req_body(),
          request_timeout=30)
