Structs

EventStore

Storage engine using an Postgres backing. This is the only persistent store currently provided.

GenericQueryRepository

This provides a simple query repository that can be used both to return deserialized views and to act as a query processor.

SnapshotEventStore

Storage engine using an Postgres backing and relying on a serialization of the aggregate rather than individual events. This is similar to the “snapshot strategy” seen in many CQRS frameworks.

Functions

get_cqrs
