event-store-design

To design an event store in PostgreSQL, use an append-only table schema with per-stream versioning to enforce immutable event logging and guarantee reliable data traceability across aggregate streams. The Skill provides concrete templates for this setup.

Comparing EventStoreDB and DynamoDB for event-sourcing involves evaluating specific architecture patterns. This Skill offers direct technology comparisons, detailing how each handles per-stream versioning, snapshots, and subscriptions to guide your choice.

Implementing snapshots and per-stream versioning requires applying specific architectural patterns to your event store, ensuring efficient querying and data consistency. This Skill covers these patterns with practical schema design and deployment guidance.

You need an event store when your application requires reliable event-sourced systems with strict data integrity, traceability, and an immutable global event feed. It solves the need for robust state reconstruction across complex domains.

DynamoDB can support event-sourced systems through specific schema templates and subscription patterns. This Skill details practical deployment guidance for implementing global event feeds and per-stream versioning within DynamoDB environments.
