Briefly

The article discusses the complexities of building multi-tenant applications in Rails, emphasizing the importance of clear data separation between tenants. It details the process of configuring shard-aware ActiveRecord models and integrating RailsEventStore with tenant-specific repositories. This integration allows for efficient management of events while maintaining data isolation. Additionally, the article addresses the challenges associated with asynchronous event handlers working across multiple shards, providing developers with practical insights and strategies to scale their applications while ensuring tenant safety.
Building a multi-tenant application requires careful planning to ensure that data separation between tenants is respected. This article provides practical strategies for implementing such structures using Rails.
Using Rails horizontal sharding allows developers to manage data across multiple database shards effectively. The article goes through the setup of shard-aware ActiveRecord models and explains key aspects.
The integration of RailsEventStore with tenant-specific repositories is crucial to maintaining the separation of events. This practice helps manage events belonging to specific tenants while ensuring that event handling works seamlessly.
