Journal plugin API
------------------
A journal plugin either extends ``SyncWriteJournal`` or ``AsyncWriteJournal``. ``SyncWriteJournal`` is an
actor that should be extended when the storage backend API only supports synchronous, blocking writes. In this
case, the methods to be implemented are:
A journal plugin extends ``AsyncWriteJournal``.
.. includecode:: ../../../akka-persistence/src/main/scala/akka/persistence/journal/SyncWriteJournal.scala#journal-plugin-api
``AsyncWriteJournal`` is an actor that should be extended if the storage backend API supports asynchronous,
non-blocking writes. In this case, the methods to be implemented are:
``AsyncWriteJournal`` is an actor and the methods to be implemented are:
.. includecode:: ../../../akka-persistence/src/main/scala/akka/persistence/journal/AsyncWriteJournal.scala#journal-plugin-api
Message replays and sequence number recovery are always asynchronous, therefore, any journal plugin must implement:
If the storage backend API only supports synchronous, blocking writes, the methods should be implemented as:
.. includecode:: code/docs/persistence/PersistencePluginDocSpec.scala#sync-journal-plugin-api
A journal plugin must also implement the methods defined in ``AsyncRecovery`` for replays and sequence number recovery:
.. includecode:: ../../../akka-persistence/src/main/scala/akka/persistence/journal/AsyncRecovery.scala#journal-plugin-api
