Deterministic SagaID generation to allow using only ID based lookups and the ID index only #802
Description
Describe the suggested improvement
Is your improvement related to a problem? Please describe.
The currently released versions of MongoDB use the default SagaIdGenerator from Core, which internally creates a comb GUID. Some persisters have moved toward overriding the saga ID generator to create a deterministic ID based on the saga entity type, the correlation property name, and the correlation property value.
This approach ensures that all saga lookups can be performed directly using the Saga ID, eliminating the need for additional indexes or member caches.
Using deterministic IDs can also improve lookup efficiency, as ID-based queries are generally fast and cost-effective. In addition, it may simplify sharding strategies by leveraging the deterministic ID.
Describe the suggested solution
Implement a SagaIdGenerator similar to the approaches used by CosmosDB, DynamoDB, or Azure Table. Provide backward compatibility for an interim period and gradually phase out the compatibility modes.
