* deprecates awaitTermination, shutdown and isTerminated
* introduces a terminate-method that returns a Future[Unit]
* introduces a whenTerminated-method that returns a Future[Unit]
* simplifies the implementation by removing blocking constructs
* adds tests for terminate() and whenTerminated
* Replace stash with internal bufferi, j.u.LinkedList
* Replace FSM with become
* Adaptive backoff, important to backoff, but not for too long,
depends on environment and use case
* Prioritize heartbeat messages from remote watcher and cluster
failure detector
* Use payload messages as heartbeats for transport failure detector,
change transport failure detector to be based on absolute timeout,
see ticket #13989 and #13742
* Log remote disassociate from transport failure detector,
see ticket #13985
* Add benchmark sample in akka-sample-remote-scala
* The problem was that the unreachability observed by second node
was leaking from previous test step and when adding the blackhole,
it could not heal and that caused the leader to not be able to remove
the downed second node because some other nodes were still marked as
unreachable.
* The first node was not included in the the awaitAllReachable check
in the previous step, and the order of awaitAllReachable and
awaitMembersUp was wrong.
* Included the awaitAllReachable check in assertCanTalk.
* Changed to two-way blackhole and using barrier instead of scheduled
event to trigger the exceptions when the blackhole was in place
* We should investigate if unreachable observations from downed node
can be excluded in the convergence check. Created separate ticket for
that 3875.
* It did not use the toString (including full address of destination) of the
node entries, instead it used the hashCode which always included the self
address
* This was a regression in 2.3, it is correct in 2.2.3
* The Identify message didn't get through to the master, which
was stopping at the same time, and it didn't got redirected to
deadletters, i.e. the "termination race"
* because it is not referentially transparent; normally we reserved parens for
side-effecting code but given how people thoughtlessly close over it we revised
that that decision for sender
* caller can still omit parens
- removed retry-window and related settings
- removed gate-invalid-addresses-for
- gate is now mandatory
- remoting has a dedicated dispatcher by default
- updated tests to work with changed timings
- added doc section for association lifecycle
* Getter for CurrentClusterState in Cluster extension, updated via
ClusterReadView
* Remove lazy init of readView. Otherwise the cluster.state will be
empty on first access, wich is probably surprising
* Subscribe to several cluster event types at once, to ensure *one*
CurrentClusterEvent followed by change events
* Deprecate publishCurrentClusterState, was a bad idea, use sendCurrentClusterState
instead
* Possibility to subscribe with InitialStateAsEvents to receive events corresponding
to CurrentClusterState
* CurrentClusterState not a ClusterDomainEvent, ticket #3614
* The previous one-way hearbeat was elegant, but comlicated to
understand and without giving much extra value compared to this approach.
* The previous one-way heartbeat have some kind of bug when joining
several (10-20) nodes at approximately the same time (but not exactly
the same time) with a false failure detection triggered by the extra heartbeat,
which would not heal.
* This ping-pong approach will increase network traffic slightly, but heartbeat
messages are small and each node is limited to monitor (default) 5 peers.
* Separate routing logic, to be usable stand alone, e.g. in actors
* Simplify RouterConfig, only a factory
* Move reading of config from Deployer to the RouterConfig
* Distiction between Pool and Group router types
* Remove usage of actorFor, use ActorSelection
* Management messages to add and remove routees
* Simplify the internals of RoutedActorCell & co
* Move resize specific code to separate RoutedActorCell subclass
* Change resizer api to only return capacity change
* Resizer only allowed together with Pool
* Re-implement all routers, and keep old api during deprecation phase
* Replace ClusterRouterConfig, deprecation
* Rewrite documentation
* Migration guide
* Also includes related ticket:
+act #3087 Create nicer Props factories for RouterConfig
* Revert the change introduced in
https://github.com/akka/akka/pull/1738/files
* The cleanup/improvements aside of the actual
feature is not reverted by this patch
* Clarify the documentation
* Replace (deprecate) akka.cluster.auto-down config setting with
akka.cluster.auto-down-unreachable-after
* AutoDown actor that keeps track of unreachable members
and performs down from the leader node when they have been
unreachable for the specified duration
* Migration guide
