features:
- >
Support for queue based communication between alarm evaluator service and
alarm notifier services was added. Original implementation involved using
RPC but there is significant overhead involved with using RPC. Work queues
provided required functionality with better performance.
upgrade:
- >
Queue based communication is the new default IPC protocol. RPC can still
be used by choosing rpc as ipc_protocol option. Only one protocol can be
run at any given time.
deprecations:
- >
Because queues provide the equivalent functionality. RPC support is
deprecated and will be removed after Mitaka.
