* 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
* 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
* ClusterCoreDaemon and ClusterDomainEventPublisher can't be restarted
because the state would be obsolete.
* Add extra supervisor level for ClusterCoreDaemon and
ClusterDomainEventPublisher, which will shutdown the member
on failure in children.
* Publish the final removed state on postStop in
ClusterDomainEventPublisher. This also simplifies the removing
process.
- Asynchronous lockless remoting
- Pluggable transport drivers
- Multiple transport support
- Simplified lifecycle events
- Support for netty based TCP, SSL+TCP and UDP support
- Updated Akka protocol with soft-state connections and failure detection
- Refactored failure detectors (currently duplicated from cluster)
* Added publishCurrentClusterState and sendCurrentClusterState
* Removed Ping/Pong that was used for some tests, since awaitCond is
now needed anyway, since publish to eventStream is done afterwards
* Major refactoring to remove the need to use special
Cluster instance for testing. Use default Cluster
extension instead. Most of it is trivial changes.
* Used failure-detector.implementation-class from config
to swap to Puppet
* Removed FailureDetectorStrategy, since it doesn't add any value
* Added Cluster.joinSeedNodes to be able to test seedNodes when Addresses
are unknown before startup time.
* Removed ClusterEnvironment that was passed around among the actors,
instead they use the ordinary Cluster extension.
* Overall much cleaner design
* Gossip is not exposed in user api
* Better and more events
* Snapshot event sent to new subscriber
* Updated tests
* Periodic publish only for internal stats
* Essentially as already described in cluster specification,
but now fully implemented and tested with LargeClusterSpec
* Gossip to nodes with different view (using seen table)
with certain probability
* Gossip chat, gossip back to sender
* Immediate gossip to joining node
* Updated some tests to reflect current implementation
* self is initially not member (in gossip state)
* if the join to seed nodes timeout it joins itself, and becomes
singleton cluster
* remove the special case handling of singelton cluster in gossip
merge, since singleton cluster is not the normal state when joining
any more
* Implement the join to seed nodes process
When a new node is started started it sends a message to all
seed nodes and then sends join command to the one that answers
first.
* Configuration of seed-nodes and auto-join
* New JoinSeedNodeSpec that verifies the auto join to seed nodes
* In tests seed nodes are configured by overriding seedNodes
function, since addresses are not known before start
* Deputy nodes are the live members of the seed nodes (not sure if
that will be the final solution, see ticket 2252
* Updated cluster.rst with latest info about deputy and seed nodes
* All members must be in seen table for convergence
* Added extra debug logging due to convergence issues
* Enabled test of convergence for node joining singleton
cluster
- Moved FailureDetectorPuppet to its own file in src/test.
- Removed 'phi' method from FailureDetector public API.
- Throwing exception instead of falling back to default if we can't load the custom FD.
- Removed add-connection method in FailureDetectorPuppet.
