Broker::__auto_publish¶

Broker::__flush_logs¶

Broker::__forward¶

Broker::__publish_id¶

Broker::__subscribe¶

Broker::__unsubscribe¶

Broker::make_event¶

Create a data structure that may be used to send a remote event via Broker::publish.

Args: an event, followed by a list of argument values that may be used to call it.
Returns: opaque communication data that may be used to send a remote event.

Broker::publish¶

Publishes an event at a given topic.

Topic: a topic associated with the event message.
Args: Either the event arguments as already made by Broker::make_event or the argument list to pass along to it.
Returns: true if the message is sent.

Cluster::publish_hrw¶

Publishes an event to a node within a pool according to Rendezvous (Highest Random Weight) hashing strategy.

Pool: the pool of nodes that are eligible to receive the event.
Key: data used for input to the hashing function that will uniformly distribute keys among available nodes.
Args: Either the event arguments as already made by Broker::make_event or the argument list to pass along to it.
Returns: true if the message is sent.

Cluster::publish_rr¶

Publishes an event to a node within a pool according to Round-Robin distribution strategy.

Pool: the pool of nodes that are eligible to receive the event.
Key: an arbitrary string to identify the purpose for which you’re distributing the event. e.g. consider using namespacing of your script like “Intel::cluster_rr_key”.
Args: Either the event arguments as already made by Broker::make_event or the argument list to pass along to it.
Returns: true if the message is sent.
