Event Sourcing Pattern

An Event Sourcing Pattern is a software architectural pattern that persists event sourcing domain state as an event sourcing immutable sequence of event sourcing state changes.

• Context:
  • It can typically reconstruct Event Sourcing Current State by replaying event sourcing historical events.
  • It can typically provide Event Sourcing Audit Trails through event sourcing event logs.
  • It can typically enable Event Sourcing Time Travel through event sourcing event replays.
  • It can typically support Event Sourcing Event Projections for event sourcing read models.
  • It can typically ensure Event Sourcing Event Ordering through event sourcing sequence numbers.
  • ...
  • It can often optimize Event Sourcing Snapshots for event sourcing replay performance.
  • It can often implement Event Sourcing Saga Patterns for event sourcing distributed transactions.
  • It can often provide Event Sourcing Event Versioning for event sourcing schema evolution.
  • It can often enable Event Sourcing Command Validation through event sourcing business rules.
  • ...
  • It can range from being a Simple Event Sourcing Pattern to being a Complex Event Sourcing Pattern, depending on its event sourcing implementation sophistication.
  • It can range from being a Domain-Specific Event Sourcing Pattern to being a Generic Event Sourcing Pattern, depending on its event sourcing application scope.
  • ...
  • It can integrate with Event Sourcing CQRS Patterns for event sourcing read model separation.
  • It can connect to Event Sourcing Event Stores for event sourcing persistence layer.
  • It can interface with Event Sourcing Message Buses for event sourcing event distribution.
  • It can coordinate with Event Sourcing Projection Engines for event sourcing view generation.
  • ...
• Example(s):
  • Event Sourcing Implementation Frameworks, such as:
    • Axon Event Sourcing Pattern Framework for event sourcing Java implementation.
    • EventStore Event Sourcing Pattern System for event sourcing database platform.
    • Eventuate Event Sourcing Pattern Framework for event sourcing microservice platform.
  • Event Sourcing Domain Examples, such as:
    • Banking Event Sourcing Pattern for event sourcing transaction history.
    • Order Management Event Sourcing Pattern for event sourcing order lifecycle.
    • Inventory Event Sourcing Pattern for event sourcing stock movement.
  • Event Sourcing Architecture Examples, such as:
    • Microservice Event Sourcing Pattern for event sourcing distributed system.
    • Blockchain Event Sourcing Pattern for event sourcing immutable ledger.
  • ...
• Counter-Example(s):
  • CRUD Pattern, which maintains current state rather than event sourcing history.
  • State Machine Pattern, which tracks state transitions without event sourcing persistence.
  • Memento Pattern, which provides snapshot restoration rather than event sourcing replay.
