Asynchronously and physically deletes events up to toSequenceNr.
Asynchronously and physically deletes events up to toSequenceNr. This operation completes when
physical deletion completed. A backend that does not support physical deletion should not override
this method.
Asynchronously batch-reads events whose destinationAggregateIds contains the given aggregateId.
Asynchronously batch-reads events whose destinationAggregateIds contains the given aggregateId. At most
max events must be returned that are within the sequence number bounds fromSequenceNr and toSequenceNr.

Synchronously writes events to the given partition.
Synchronously writes events to the given partition. The partition is calculated from the configured
partitionSizeMax and the current sequence number. Asynchronous writes will be supported in future versions.
This method may only throw an exception if it can guarantee that events have not been written to the storage
backend. If this is not the case (e.g. after a timeout communicating with a remote storage backend) this method
must retry writing or give up by stopping the actor with context.stop(self). This is necessary to avoid that
events are erroneously excluded from the event stream sent to event-sourced actors, views, writers and
processors, as they may later re-appear during recovery which would violate ordering/causality guarantees.
Implementations that potentially retry a write for a longer time should use a CircuitBreaker for protecting themselves against request overload.
Synchronously writes metadata for a Delete request.
Synchronously writes metadata for a Delete request. This marks events up to DeletionMetadata.toSequenceNr as deleted, i.e. they are not read on replay and indicates which remote logs must have replicated these events before they are allowed to be physically deleted locally.
Asynchronously writes the replication progress for given source logId.
Asynchronously writes the replication progress for given source logId.
An event log actor with LevelDB as storage backend. The directory containing the LevelDB files for this event log is named after the constructor parameters using the template "
prefix-id" and stored in a root directory defined by thelog.leveldb.dirconfiguration.Please note:
prefixandidare currently not escaped when creating the directory name.
