Relation Repository
The Relation Repository is responsible for storing and retrieving relationships between roles. A relation refers to a connection between two roles. A relation is established as soon as two IPersist roles play a role in the same scenario. Combinations are unique, meaning roleid1=xyz and roleid2=abc is equivalent to roleid1=abc and roleid2=xyz.
Types of Persisted Role Repositories
Similar to the Persisted Role Repository, there are two standard implementations for the Relation Repository in Backlot: the Memory Relation Repository and the RavenDB Relation Repository.
Memory Repository
The Memory Relation Repository stores relations in-memory, which means the data is volatile and lost upon application shutdown or restart. This is ideal for rapid development cycles, testing scenarios, or situations where relation data persistence beyond application sessions is unnecessary.
Use the following code in the Program.cs to configure the Memory Relation Repository:
RavenDB Repository
The RavenDB Relation Repository stores relations in RavenDB, a high-performance, distributed, NoSQL document database. In addition to its NoSQL capabilities, RavenDB is also an ACID-compliant database, which is unlike many other NoSQL databases. This provides durable storage for relations across application sessions and is suited for production environments requiring robust, scalable, and durable storage solutions for relation data.
Use the following code in the Program.cs to configure the RavenDB Relation Repository:
