Ivan Andika updated RATIS-2196:
-------------------------------
Description:
Some of the StateMachine notification APIs are run sequentially in very
important parts of the code (e.g. StateMachineUpdater). This carries a few
risks:
* If the notification API implementation takes very long, it might cause the
StateMachine performance to suffer
* Exception thrown in this notification APIs might cause the whole
StateMachine to be
One idea is to make this notification API asynchronous. For example, by having
a specific ExecutorService to run the notifications, or just do a "fire and
forget" method.
One downside is that if the StateMachine implementation relies on the
sequential nature of the StateMachine notification API, it might not be wise to
make this asynchoronous.
We can discuss whether making the notification API asynchronous make sense.
