shop

The complete distributed service of V.5: users, orders and carts; checkout as a saga with an external warehouse and payments; photo upload through a pipeline on a GPU; order events through a topic; live statistics. Five roles (api, storage, saga, gpu, ml) in one binary.

oxl test examples/shop                       # unit tests, mocks of the warehouse and payments
oxl test examples/shop --kind sim            # simulation of a saga node crash, 300 seeds
oxl test examples/shop --kind ab             # the A/B experiment test ab "search v2"
oxl dev --nodes 5 examples/shop              # a cluster of five nodes
