StreamStore

Asynchronous event sourcing.

Library provides a logical layer for storing and querying events as a stream.

Heavily inspired by Greg Young's Event Store and Streamstone solutions.

Overview

Designed to be easily extended with custom storage backends. Despite the fact that component implements a logical layer for storing and querying events as a stream, it does not provide functionality of DDD aggregate, such as state mutation, conflict resolution etc., but serves more as persistence layer for it.

Packages

Name Description Package
StreamStore Asynchronous event streaming NuGet version (StreamStore)
StreamStore.Storage Base implementation of storage NuGet version (StreamStore.Testing)
StreamStore.Serialization.Protobuf Protobuf event serializer NuGet version (StreamStore.Testing)

Storage packages

Name Description Concurrency Control Multitenancy Event Duplication Detection Package
StreamStore.NoSql.Cassandra Apache Cassandra and Azure Cosmos DB for Apache Cassandra storage Optimistic ✅ ❌ NuGet version (StreamStore.NoSql.Cassandra)
StreamStore.Sql.PostgreSql PostgreSQL storage Optimistic ✅ ✅ NuGet version (StreamStore.Sql.PostgreSql)
StreamStore.Sql.Sqlite SQLite storage Optimistic ✅ ✅ NuGet version (StreamStore.Sql.Sqlite)
StreamStore.InMemory In-memory storage is provided for testing and educational purposes only Optimistic ✅ ✅ NuGet version (StreamStore.InMemory)
StreamStore.S3.AWS Amazon S3 storage Pessimistic :x: ❌ NuGet version (StreamStore.S3.AWS)
StreamStore.S3.B2 Backblaze B2 storage (not working at the moment!) Pessimistic :x: ❌ NuGet version (StreamStore.S3.B2)

Features

The general idea is to highlight the common characteristics and features of event sourcing storage:

  • Asynchronous read and write operations.
  • Multitenancy support.
  • Automatic provisioning of storage schema.
  • Event ordering.
  • Serialization/deserialization of events.
  • Optimistic concurrency control.
  • Event duplication detection based on event ID.
  • Storage agnostic test framework, including benchmarking test scenarios.
  • Binary serialization support.
  • Custom event properties.
