pandagg.connections module¶
-
class
pandagg.connections.
Connections
[source]¶ Bases:
object
Class responsible for holding connections to different clusters. Used as a singleton in this module.
-
configure
(**kwargs)[source]¶ Configure multiple connections at once, useful for passing in config dictionaries obtained from other sources, like Django’s settings or a configuration management tool.
Example:
connections.configure( default={'hosts': 'localhost'}, dev={'hosts': ['esdev1.example.com:9200'], 'sniff_on_start': True}, )
Connections will only be constructed lazily when requested through
get_connection
.
-
create_connection
(alias='default', **kwargs)[source]¶ Construct an instance of
elasticsearch.Elasticsearch
and register it under given alias.
-
get_connection
(alias='default')[source]¶ Retrieve a connection, construct it if necessary (only configuration was passed to us). If a non-string alias has been passed through we assume it’s already a client instance and will just return it as-is.
Raises
KeyError
if no client (or its definition) is registered under the alias.
