An application to calculate shipping cost based on Dijkstra algorithm

Redis is used as cache to store calculated routes and Sidekiq to recalculate routes when an edge is created or changed, trying to avoid calculate dijkstra when the shipping cost is requested. This solution has inspirations in CQRS and eventual consistency.
