The EAE engine is a runtime environment hosted in an EG i.e. at the edge of a FAR-EDGE deployment. It is the programmable and configurable environment that executes data analytics logic locally in order to meet stringent performance requirements, mainly in terms of latency. The EAE is in charge of data analytics within a single EG. The EAE is also configurable while comprising multiple analytics instances that are driven by multiple smart contracts.
