eventsourcing/es4j
This system is an event sourcing library that provides a complete infrastructure for building event-sourced applications, including core abstractions for commands, events, and repositories. It supports multiple storage backends, specifically PostgreSQL and in-memory stores, with robust indexing and query capabilities. The system also features hybrid logical clocking for precise event ordering and includes utilities for schema migrations and rule-based automation.
