endless4s/endless

Endless is a Scala library that provides abstractions for building event-sourced and durable state repositories. It enables the creation of sharded, cluster-based entity models with support for both Akka and Pekko runtimes. The system handles command serialization via Protobuf and Circe, and manages entity lifecycle, passivation, and side effects. An example application demonstrates these capabilities with booking and vehicle domain models.

The project established foundational abstractions for event-sourced and durable entities, replacing previous persistence layers with new core types like EntityT and DurableEntityT. This period also introduced concrete protocol implementations for Circe and Protobuf, alongside a comprehensive example application demonstrating booking and vehicle domain logic. The work was supported by extensive test coverage and updated build tooling to align with Scala 2.13.

This period focused on implementing runtime adapters for both Akka and Pekko, enabling sharded entity management and cluster-aware serialization. The work included adding Protobuf definitions, serializers, and HTTP API endpoints to demonstrate durable state and event sourcing capabilities across both actor frameworks.
