Subscription engine for event-sourced systems

Usage

This package contains base types and interfaces for Subscription Engines. In order to use it, implementations for the following interfaces have to be provided:

SubscriptionStore

The SubscriptionStore allows to persist and update the state of subscriptions and allows to lock access such that multiple processes cannot change the same subscription at the same time.

Implementations

• wwwision/subscription-engine-doctrine provides a DBAL implementation that is compatible with MySQL/MariaDB, PostgreSQL and SQLite.
• ekvedaras/subscription-engine-illuminate provides an implementation that uses Laravel database.

EventStoreAdapter

The EventStoreAdapter is the adapter for the actual event store implementation

Implementations

• wwwision/subscription-engine-neos-adapter - adapter for the neos/eventstore
• wwwision/subscription-engine-dcb-adapter - adapter for the wwwision/dcb-eventstore
