The signature is def asyncWriteMessages(messages: immutable.Seq[AtomicWrite]): Future[immutable.Seq[Try[Unit]]]
If the future is completed with exception it is the failure case, otherwise it’s possible to reject individual events as documented: * The journal can also signal that it rejects individual messages (`AtomicWrite`) by * the returned `immutable.Seq[Try[Unit]]`. It is possible but not mandatory to reduce * number of allocations by returning `Future.successful(Nil)` for the happy path, * i.e. when no messages are rejected. Otherwise the returned `Seq` must have as many elements * as the input `messages` `Seq`. Each `Try` element signals if the corresponding * `AtomicWrite` is rejected or not, with an exception describing the problem. Rejecting * a message means it was not stored, i.e. it must not be included in a later replay. * Rejecting a message is typically done before attempting to store it, e.g. because of * serialization error. * https://doc.akka.io/docs/akka/current/persistence.html#storage-plugins /Patrik lör 27 jan. 2018 kl. 02:36 skrev Andrey Ilinykh <ailin...@gmail.com>: > Thank you very much! > > > >> For rejected the PA continues.
