PersistencePluginProxyExtension is an IExtension that enables initialization of the PersistencePluginProxy via configuration, without requiring any code changes or the creation of any actors.

ReplayFilter

Detect corrupt event stream during replay. It uses the WriterGuid and the SequenceNr in the replayed events to find events emitted by overlapping writers.

Structs

The journal may support tagging of events that are used by the EventsByTag query and it may support specifying the tags via an IEventAdapter that wraps the events in a Tagged with the given Tags. The journal may support other ways of doing tagging. Please consult the documentation of the specific journal implementation for more information. The journal will unwrap the event and store the Payload.

IEventAdapter

An IEventAdapter is both a IWriteEventAdapter and a IReadEventAdapter. Facility to convert from and to specialised data models, as may be required by specialized persistence Journals.

Typical use cases include (but are not limited to):

- adding metadata, a.k.a. "tagging" - by wrapping objects into tagged counterparts

- manually converting to the Journals storage format, such as JSON, BSON or any specialised binary format

- adapting incoming events in any way before persisting them by the journal

IEventSequence

TBD

IReadEventAdapter

Facility to convert from specialised data models, as may be required by specialized persistence Journals.

Typical use cases include (but are not limited to):

- extracting events from "envelopes"

- manually converting to the Journals storage format, such as JSON, BSON or any specialised binary format

- adapting incoming events from a "data model" to the "domain model"

IWriteEventAdapter

Facility to convert to specialised data models, as may be required by specialized persistence Journals.

Typical use cases include (but are not limited to):

- adding metadata, a.k.a. "tagging" - by wrapping objects into tagged counterparts

- manually converting to the Journals storage format, such as JSON, BSON or any specialised binary format

- splitting up large events into sequences of smaller ones
