+ per plugin scoped adapters
+ could be swapped during runtime
+per EventAdapter now has manifest and is configurable ai la serializers
+ json examples in docs
+ including "completely manual" example in case one wants to add
metadata TO the persisted event
+ better error reporting when misconfigured bindings
+ manifest is handled by in memory plugin
- did not check if it works with LevelDB plugin yet
> TODO: json example uses Gson, as that's simplest to do, can we use
+per allows 1:n adapters, multiple adapters can be bound to 1 class
* I think it originated from channels, or some idea that
the sender should be revived (as good as possible) during replay,
but that is pretty useless
* It must still be in PersistentRepr for remote serialization
* I didn't want to change to the built in sender when looping to the
journal because keeping it together with the message makes it easier
to do batching (queueing)
* adjust tck
* remove channels
* remove View
* remove Processor
* collapse the complicated internal state management
that was spread out between Processor, Eventsourced and Recovery
* remove Recovery trait, this caused some duplication between Eventsourced
and PersistentView, but but the enhanced PersistentView will not be based
on recovery infrastructure, and therefore PersistentView code will be replaced anyway
* remove PersistentBatch
* remove LoopMessage
* remove deleteMessages of individual messages
* remove Persistent, PersistentRepr and PersistentImpl are kept
* remove processorId
* update doc sample code
* note in migration guide about persistenceId
* rename Resequencable to PersistentEnvelope
* also remove final of around methods, and let deliver send when not recoveryRunning
(cherry picked from commit 312b0d107a179accaf135f64ed9c3b78f3e351d1)
* This is NOT binary compatible, we're in an *experimental* module.
* disabled binary compat checks for package akka.persistence
* Source compatibility is retained, but users should migrate do the new
method name ASAP.
* Plugin APIs were migrated in a way that allows the old plugins to
compile agains 2.3.4 without having to change anything. Hopefuly this
will help authors migrate to 2.3.4 sooner. This is only source level compatible, not binary compatible.
* added deprecation warnings on all processorId methods and provided bridges where possible
* for users, the migration should be painless, they can still override
the old method, and it'll work. But we encourage them to move to
persistenceId; All delegation code will have to be removed afterwards ofc.

- Built-in redelivery mechanism for Channel and PersistentChannel
- redelivery counter on ConfirmablePersistent
- redeliveries out of initial message delivery order
- relative order of redelivered messages is preserved
- configurable redelivery policy (ChannelSettings)
- Major refactorings of channels (and channel tests)
- Throughput load test for PersistentChannel
Todo:
- Paged/throtlled replay (another pull request)
- Resequencer (another pull request)
- Persistent channel
- ConfirmablePersistent message type delivered by channel
- Sender resolution performance improvements
* unstash() instead of unstashAll()
These enhancements required the following changes
- Unified implementation of processor stash and user stash
- Persistence message plugin API separated from implementation
- Physical deletion of messages
- batch-write of persistent messages (user API)
- batch-write of events (in EventsourcedProcessor)
- command processing in EventsourcedProcessor by unstashing messages one-by-one from the internal stash
* fixes performance issues that come up with unstashAll
- commands are not looped through journal actor but processed directly
- initial performance tests
* command sourcing
* event sourcing
* event sourcing with user stash operations
- suppress stack traces in tests
