fabriziosestito/commanded-spear-adapter

This system is an event-sourcing infrastructure library built on Elixir, utilizing the Commanded framework and the Spear library to interact with an EventStoreDB database. It manages the persistence and retrieval of domain events, supporting advanced features like stream prefixing, system event filtering, and snapshot serialization. The codebase includes a comprehensive test suite that automates the management of the EventStoreDB container for reliable integration testing.

The adapter has been renamed and refactored to use the Spear library instead of Extreme. This includes renaming the adapter modules from \extreme\ to \spear\, updating the connection and subscription management to use Spear's API, and adjusting how events are read, filtered, and acknowledged. The change also introduces support for \stream\_prefix\ configuration and adds a \nack\ method for subscription handling.

The Spear adapter now passes a \stream\_prefix\ to the subscription supervisor, enabling optional prefixing for stream names and snapshot streams. The \stream\_name\ helper is updated to conditionally apply the prefix, and \snapshot\_stream\_name\ is similarly adjusted. Additionally, the adapter now excludes system events from streams using a new \spear\_filter\ helper, and the \stream\_forward\ function uses a \chunk\_size\ parameter instead of \count\, while also mapping events through a stream for efficiency.

The project now requires Elixir 1.14.3 and Erlang/OTP 25.2.2, up from Elixir 1.13.1 and OTP 24. This upgrade ensures compatibility with newer versions of the \spear\ library and other dependencies, and may require developers to update their local development environments to match these runtime versions.

(repo-wide) · high confidence

Expanded test coverage for the Spear event store adapter; Refactored test infrastructure to use transient Docker containers for EventStore; Updated test configuration to exclude partition tests.

The project updates its core dependencies to align with EventStoreDB 23.10 support. Commanded is upgraded to version 1.4 (specifically 1.4.2), and the Spear adapter is updated to version 1.4.0. Additionally, the HTTP client library Httpoison is upgraded to version 2.0.0, and the test framework Mox is updated to 1.1.0. The build tooling is also refreshed, with Credo moving to 1.7.4, Dialyxir to 1.4.3, and ExDoc to 0.31.1. New test dependencies, including excontainers and ex\_check, are added to support transient Docker containers in the test suite.
