Overview ¶
Package arke is an ultralight pub-sub system designed to be used as a message routing core for loosely coupled applications.
See package "arke/interchange" for the core API and "arke/server" for details related to providing extra-process interfaces, including a daemonizeable Arke server.
The Hub ¶
The central element of Arke is the hub. The hub manages all system events, whether that be publication, subscription, cancellation, what-have-you. The primary means of interacting on a hub is via a Client interface.
Topics ¶
Topics in Arke are dot-delimeted strings like
"foo.bar.baz"
These strings form a hierachy used during publication. For example, if there exist two subscribers, Subscriber A on "foo.bar" and Subscriber B on "foo.baz". When a Publisher C publishes on "foo" then both A and B will receive this publication.
Performance ¶
Arke is optimized for publication. This means that when there is a performance trade-off between supporting publication or subscription, publication will win out.
