# Event Store
The library provides a simple
interface that allows you to interact with Azure Cosmos DB as an event store.
This interface is the
IEventStore<TEventItem>, this allows you to save events, save aggregate roots that holds events. Read all events, stream events using
IAsyncEnumerable<T> and query events to limit the set of events that are returned.
The event store also handles the polymorphic serialization and de-serialization. This is done via a customer
JsonConverter<T>. This library currently uses
Newtonsoft.Json as this is what the underlying Cosmos DB SDK supports as of writing this.
