All spatial services in the Spectrum Technology Platform are deployed into a remote component (JVM instance) that is separate from the platform runtime. This ensures the platform is independent of the modules within it and that JVM configuration can be applied to the spatial services, allowing flexibility of memory allocation and tuning for performance based on the characteristics of those services.
The remote component supplies spatial functions to spatial services (such as the Feature Service and Mapping Service) and stages (such as the Spatial Calculator and Query Spatial Data). The pool size for a remote component is the number of requests the component can handle concurrently. This affects the throughput of both spatial services and spatial stages.
