pysage is a high-level message passing library supporting actor based
concurrency. It also extends the "actor model" to support actor
partitioning/grouping to further scalability. pysage has a simple
high-level interface. Messages are serialized and sent light-weight using
pipes or domain sockets across local "groups". In the case of network messages,
UDP is used.
* simple pythonic API
* efficient message propagation within group, across group, across network
* network messages can optionally be configured to be reliable
and/or ordered using UDP
* grouping - actors can be partitioned into groups that are run in
separate os processes
* process-local singleton manager - actor registration, discovery,
message propagation
* publisher/subscriber pattern built-in
