Nodes

.. py:currentmodule:: elastic_transport
Configuring nodes
-----------------
.. autoclass:: elastic_transport::NodeConfig
:members:
Node classes
------------
.. autoclass:: Urllib3HttpNode
:members:
.. autoclass:: RequestsHttpNode
:members:
.. autoclass:: AiohttpHttpNode
:members:
.. autoclass:: HttpxAsyncHttpNode
:members:
Custom node classes
-------------------
You can define your own node class like so:
.. code-block:: python
from typing import Optional
from elastic_transport import Urllib3HttpNode, NodeConfig, ApiResponseMeta, HttpHeaders
from elastic_transport.client_utils import DefaultType, DEFAULT
class CustomHttpNode(Urllib3HttpNode):
def perform_request(
self,
method: str,
target: str,
body: Optional[bytes] = None,
headers: Optional[HttpHeaders] = None,
request_timeout: Union[DefaultType, Optional[float]] = DEFAULT,
) -> Tuple[ApiResponseMeta, bytes]:
# Define your HTTP request method here...
and once you have a custom node class you can pass the class to :class:`elastic_transport.Transport` or an API client like so:
.. code-block:: python
# Example using a Transport instance:
from elastic_transport import Transport
transport = Transport(..., node_class=CustomHttpNode)
# Example using an API client:
from elasticsearch import Elasticsearch
client = Elasticsearch(..., node_class=CustomHttpNode)
