- Refactored the part associated to the `failForOpenCircuit` extension to Future was done.
- Moved implicit conversion into a specific class. Not requiring anymore the `._` import but importing only the implicit conversion needed
- Added a `askWithCircuitBreaker` approach to replace the ask and the following `failForOpenCircuit`
- Compacted all samples in the same file and added the copyright header
- Improved documentation
- Added handling of termination of target actor
- Introduced a Passthrough command type to allow sending message to the target actor in any state. It is intended for control messages such as `PoisonPill` or `Kill`
- Move all entry related logic out of the ShardRegion and into a
new dedicated child `Shard` actor.
- Shard actor persists entry started and passivated messages.
- Non passivated entries get restarted on termination.
- Shard Coordinator restarts shards on other regions upon region failure or handoff
- Ensures shard rebalance restarts shards.
- Shard buffers messages after an EntryStarted is received until state persisted
- Shard buffers messages (still) after a Passivate is received until state persisted
- Shard will retry persisting state until success
- Shard will restart entries automatically (after a backoff) if not passivated and remembering entries
- Added Entry path change to the migration docs
Breaks binary compatibility because adding new methods to Eventsourced
trait. Since akka-persistence is experimental this is ok, yet
source-level compatibility has been perserved thankfuly :-)
Deprecates:
* Rename of EventsourcedProcessor -> PersistentActor
* Processor -> suggest using PersistentActor
* Migration guide for akka-persistence is separate, as wel'll deprecate in minor versions (its experimental)
* Persistent as well as ConfirmablePersistent - since Processor, their
main user will be removed soon.
Other changes:
* persistAsync works as expected when mixed with persist
* A counter must be kept for pending stashing invocations
* Uses only 1 shared list buffer for persit / persistAsync
* Includes small benchmark
* Docs also include info about not using Persistent() wrapper
* uses java LinkedList, for best performance of append / head on
persistInvocations; the get(0) is safe, because these msgs only
come in response to persistInvocations
* Renamed internal *MessagesSuccess/Failure messages because we kept
small mistakes seeing the class "with s" and "without s" as the same
* Updated everything that refered to EventsourcedProcessor to
PersistentActor, including samples

ActorRef #15209
* Changed ClusterSharding.start to return the ActorRef to the shardRegion (#15157)
* Fixed indentation, and removed unused import
* Test for new API
* removed unused import
- Moved barrier outside of the runon
* 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
if the message should be sent to a matching path on the sender node or not.
Added optional property (skipSenderNode) to PubSub.SendToAll.
Deciding if the SendToAll message should be sent to a matching path on the sender cluster node or not. + Test and Docs.
* Assign internal upNumber when member is moved to Up
* Public API Member.isOlder
* Change cluster singleton to use oldest member instead of leader
* Update samples and docs
* Message wrappers in ClusterClient, so that DistributedPubSubMediator
is not leaking to the client api
* Register methods in ClusterReceptionistExtension, for convenience and
clarity
