An event store is an append-only, ordered, versioned, and subscribable persistence mechanism that captures domain events for event-sourced systems. It enables reconstructing application state by sequentially replaying stored events through the data flow architecture.

Designing a PostgreSQL event store schema involves creating append-only tables that enforce event ordering and versioning. This skill provides SQL schema templates and Python code examples to implement a robust PostgreSQL-based event store for domain-driven design.

When implementing an event store, comparing EventStoreDB and PostgreSQL involves evaluating purpose-built event sourcing features against relational database flexibility. This skill provides a technology comparison covering EventStoreDB, PostgreSQL, Kafka, DynamoDB, and Marten to guide your architecture choice.

Yes, you can use DynamoDB to build an event-sourced system by leveraging its append-only and ordered data persistence capabilities. This skill provides specific implementation templates and usage examples for setting up a DynamoDB event store.

Core requirements for event store persistence in domain-driven design include supporting append-only writes, strict event ordering, version tracking, and subscriptions. This skill addresses these architectural patterns to ensure scalable and maintainable event-sourced systems.
