Event sourcing

Framework overview

• Implementation of the event sourcing desing pattern
  • Event store
  • Implementation of the outbox design pattern
  • Event subscriber pipeline
    • Both inline and asynchronously, analog to Marten.NET
  • Aggregates
    • Construction via replay using either
      • Static factory methods
      • Aggregate constructors
      • Aggregate factory as a service
  • Snapshotting
  • Full configuration via configuration-builders or attributes
• Abstractions for those implementations
• SQL-specific implementations of persistence abstractions
• Drivers for database systems:
  • SQLite
  • PostgreSQL
  • MS SQL Server
