commanded/eventstore

This system is an Elixir-based event sourcing library backed by PostgreSQL, designed to manage event streams and subscriptions. It provides core capabilities for appending, reading, and subscribing to events, along with snapshot management and multi-node cluster support. The system includes comprehensive tooling for database migrations, performance benchmarking, and extensive test coverage for its storage and notification layers.

This period marks the initial release of the EventStore library for Elixir, establishing the foundational structure for an event sourcing system backed by PostgreSQL. The work focused on implementing core features including the event store macro, SQL schema initialization, and the complete storage layer for event persistence and subscription management. Comprehensive test coverage was added to validate the new functionality across streams, subscriptions, and storage operations.

This period focused on enabling multi-node cluster configurations and implementing a PostgreSQL-based notification system for low-latency event propagation. The work included adding cluster node configuration files, database schema migrations, and a GenStage-based listener/publisher architecture for handling stream changes. Additionally, the codebase was refactored to support multiple event stores and included comprehensive testing for the new notification and subscription systems.
