Partial State Deferral (Erl)
How can services be designed to optimize resource consumption while still remaining stateful?
Problem
Service capabilities may be required to store and manage large amounts of state data, resulting in increased memory consumption and reduced scalability.
Solution
Even when services are required to remain stateful, a subset of their state data can be temporarily deferred.
Application
Various state management deferral options exist, depending on the surrounding architecture.
Impacts
Partial state management deferral can add to design complexity and bind a service to the architecture.
Principles
Architecture
Inventory, Service
Applying this pattern results in the same amount of concurrent service instances but less overall state-related memory consumption.
